Fisher and Baron Cohen welcome baby girl

Isla Fisher and Sacha Baron Cohen have welcomed the arrival of a new baby girl.

The Wedding Crashers actress gave birth in Los Angeles on Wednesday night, according to unconfirmed reports in her native Australia.

She has been engaged to Baron Cohen, the man behind characters Borat and Ali G, since 2004, but the couple have yet to set a date for their wedding.

Fisher previously revealed that she plans to take a break from work after the birth, saying: "As far as I am concerned, I am fully booked up in my personal life and I can't see beyond that. I plan on just colouring in books. I'll focus on that for the next few years."
