Madonna borrows little Lourdes' geeky style as tour rolls into NYC

At 50, Madonna appears more eager than ever to prove she's still down with the kids.

The pop star is now apparently taking style cues from her daughter Lourdes, emerging on stage in New York last night wearing her oversized black-framed specs.

Lourdes, who at just 11 already has her own distinct fashion style, was spotted wearing the pair earlier this year before her mother managed to get her clutches on them.

Madonna's performance last night was the first of three sold-out nights in Madison Square Garden on her Sticky & Sweet world tour.

She powered through the 23-song set which chronicled her stellar career, from '80s hits to songs from this year's release Hard Candy.

This, her seventh tour, has proved incredibly profitable for the star, who has already raked in $120 million.
