Isla Fisher's fun day at the park with Baby Borat turns to tears

A fun day out of the park quickly turned sour for new mum Isla Fisher when her daughter Olive started screaming.

Like many new mothers before her, the embarrassed Wedding Crashers actress couldn't wait to leave the park when the 11-month-old began crying.

Baby Olive started the afternoon laughing on the swings as she was pushed by her devoted mother, but her happy demeanour quickly descended into tears.

The Australian actress quickly whipped Olive off the swings and took the cranky child back to the Beverly Hills mansion she shares with her fiance Sacha Baron Cohen for a nap.

Isla, 32, has been enjoying the summer off work with baby Olive and Ali G star Sacha after filming Confessions Of A Shopaholic earlier this year, which is due for release in February.

Last month, the happy family joined celebrity friends Courteney Cox, David Arquette, Leonardo DiCaprio and Tobey Maguire on a yacht in Hawaii.

While Isla has been balancing her career and family duties, English comedian Sacha's Hollywood career has boomed following the huge success of Borat: Cultural Learnings of America for Make Benefit Glorious Nation of Kazakhstan two years ago.

Sacha has four projects in the pipeline, including a comedy about his gay Austrian TV presenter character Bruno.

Sacha, 36, proposed to Isla in 2004 after dating for four years prior, but the couple are yet to announce a wedding date.

The couple's marriage will have to wait until Isla is fully converted to Judaism, Sacha's religion.

They say when you have children it can bring out your playful side.

For Isla Fisher, she needs no encouragement.

While on a break in Hawaii, the Australian actress could not resist showing off her gymnastic prowess by performing a cartwheel on the beach.

Fisher, who is used to being seen by a cinema audience of millions, was this time performing for a much smaller crowd - fiance Sacha Baron Cohen and their 10-month-old daughter Olive.

The Wedding Crashers star, 32, looked a picture of happiness in a thinly-strapped red swimming costume, as she enjoyed some playtime in the sun.

It's been a busy year for the diminutive star.

In the past 12 months, she has given birth to her first child and played the lead role in the movie Confessions Of A Shopaholic.

And after appearing in two romantic comedies about weddings, there had been talk that Fisher and Baron Cohen were due to tie the knot this summer.

However for now, the Hollywood-based couple who have been engaged since 2004, appear to have put their nuptials on hold and spend some quality time with baby daughter.

Sacha Baron Cohen and Isla Fisher's wedding on hold

Sacha Baron Cohen and fiancee Isla Fisher have been forced to postpone their wedding over religious issues, MailOnline has learned.

The Hollywood-based couple, who welcomed a daughter last year, originally planned to tie the knot later this summer.

But they have decided to delay the nuptials because Isla, 32, has yet to convert to the Ali G star's faith of Judaism.

Postponed: Isla Fisher and comedian Sacha Baron Cohen, here at last year's Oscars, have been forced to delay their wedding as the actress has not yet converted to her fiance's Jewish religion

A source said: 'Isla was supposed to spend her time after giving birth hard at work on her Torah studies, and that's gone far slower than expected.

'It's very much frustrated her future in-laws, especially Sacha's parents, who were really hoping for a wedding this summer.'

The source added: 'Right now there's no wedding date set because Isla hasn't fully converted yet, and even though she's working at it part-time, she's far from being close to completing her studies.'

Isla, who has spent most of this summer filming her upcoming project Confessions Of A Shopaholic, is said to have a tense relationship with Sacha's mother, Daniella.

The source said: 'What made relations difficult between Isla and Sacha's mother is that she really wanted Isla to spend more time with the baby and their family in England instead of being hasty and returning to work so quickly.

'Now that Isla's done shooting, she's in the awkward position of making up for lost time.'

To this end, the Australian-born actress, who found fame in Home And Away in the Nineties, is spending increasing amounts of time with her in-laws in Britain, in an apparent effort to endear herself to them.

Meanwhile the notoriously reclusive Baron Cohen, 36, is patiently playing peacemaker between his wife and mother.

Instead of wedding preparations, he has channelled his energies into work, chalking up long hours on his new reality-based film Bruno, which has nearly completed filming and will be released worldwide next summer.

The source said: 'Sacha is not as worried about the relationship between his parents and Isla as everyone else is because he's extremely devoted to her and their child.

'He also believes that putting too much pressure on Isla is only going to make the wedding happen later rather than sooner.

'He is happy taking his time to get married the same way he was happy having a long engagement.

'But in the meantime Isla's had to endure a lot of awkward moments with Sacha's mother, who just doesn't seem to understand her future daughter-in-law's drive to become a big star.'

For Isla's part, the actress is said to be looking forward to becoming a Cohen.

The source said: 'No matter what Sacha's mother throws at her, Isla isn't going to be scared away from the relationship or the family.

'You really get the sense that her devotion to Sacha is total, even if she's stalled a little bit on her Jewish studies. She loves sharing her life with this guy.'

Has Borat's love Isla had her bust boosted for new film?

Her baby bump has long disappeared, but Isla Fisher is not short on curves.

The actress, who swiftly regained her slim waistline after giving birth to daughter Olive four months ago, appears to have enjoyed a rather impressive boost to her chest.

Her newly buxom physique was on display while filming Confessions Of A Shopaholic in New York yesterday.

Isla, who is engaged to Borat star Sacha Baron Cohen, recently revealed she has a secret weapon to a slender waistline, confessing rather frankly to using control pants.

Asked how she regained her figure, the 32-year-old said: "Spanx! You know them? It's night and day!"

Thinking pink: Isla says she's 'so excited' about her new film role

Despite insisting work is no longer "as big a priority" since giving birth, she has said she is "so excited" about her new Hollywood role.

She has taken the lead role in a adaptation of Sophie Kinsella's novel series about a compulsive shopper in serious debt who becomes a financial advice columnist.

She has said: "I loved those books. I'm such a Sophie Kinsella fan. She's such a talented writer, and it taps into the consumer collective conscience."

"I've done a lot of research — a lot of shopping."

Isla Fisher's Action Ban

Pregnant Isla Fisher was banned from doing stunts in her new film 'Hot Rod'.

The Australian actress wasn't even allowed to film a scene where she was standing on a moped, because the crew were worried something could go wrong with her pregnancy.

She said: "They wouldn't even let me do that one scene where you see me standing on the moped. They only let me do the drive up and the turn, and then the stuntwoman took over. At least, I hope it was a woman in a red wig, but it may have been a man!"

The 31-year-old star - who is expecting a baby with her fiancé, Sacha Baron Cohen - also explained why she tried to keep the pregnancy a secret.

She told Britain's The Independent newspaper: "In the beginning, I dodged the rumours. I was trying not to be rude, but there's a time before you're sure everything is all right with no complications that you just don't want to discuss it."
