It’s been four months since the arrival of baby Olive. Here’s Isla Fisher in New York last night for the premiere of Definitely, Maybe which according to advance preview audiences is adorable.

Word is Isla has slimmed down quickly for her wedding. She was cute in an interview recently, when asked if she’ll invite her Wedding Crashers co-stars, she said she would not on purpose just to see if they’d end up crashing it anyway.

Can you imagine Vince Vaughn crashing Ali G’s wedding?
