Isla Fisher and Sacha Baron Cohen have named their newborn daughter Olive.

Isla and fiance Sacha, who welcomed their first child into the world in Los Angeles last Wednesday, are said to have finally agreed on the baby's name.

Isla Fisher and Sacha Baron Cohen have become parents for the first time. The 'Wedding Crashers' actress reportedly gave birth to a girl last week and both mother and baby are said to be doing well.

'Borat' star Sacha is "thrilled" with the new arrival and has been a hands-on dad since the birth. Isla and Sacha got engaged in 2004 although they are still to set a wedding date.

Isla Fisher will never star in a movie with fiance Sacha Baron Cohen, because working together "is the kiss of death."

The 31-year-old Australian actress - who is expecting her first child with the 'Borat...' actor in October - has no plans to follow in the footsteps of previous couples such as Nicole Kidman and Tom Cruise, or Ben Affleck and Jennifer Lopez and share a screen with her partner, because it always ends in disaster.

Courteney Cox and David Arquette have been voted the celebrity couple most likely to succeed.

The pair - who have been married for eight years and have a three-year-old daughter, Coco, together - received a staggering 59 percent of the vote in Parade.com's Pop Culture Survey Summer 2007.

"Borat" is going to have a baby!

British comedian Sacha Baron Cohen and his Australian fiancee Isla Fisher are expecting a baby at the end of the year.
