Bad news for Ashley: Cheryl Cole steps out in LA without her wedding ring

As she stepped out in Los Angeles yesterday, her wedding ring was noticeably absent from her left hand for the second day in a row.

Cheryl is expected to return to the UK early this week ahead of the Brit Awards on Wednesday.
