Isla, 31, gave birth to their first child last week last Wednesday, Oct. 17, in Los Angeles, but Sacha didn’t confirm the happy news until Tuesday.

“They had a beautiful healthy baby girl. Mother and daughter are doing great,” a rep for the couple said.

The very pregnant Isla Fisher (due any minute now) leaves a Beverly Hills restaurant Thursday night after having dinner with comedian fiance Sacha Baron Cohen.

Isla, 31, and Sacha, 35, at first didn’t admit to pregnant rumors because they were fearful of complications with the baby.

Said Isla, “In the beginning, I dodged the rumors. I was trying not to be rude, but there’s a time before you’re sure everything is all right with no complications that you just don’t want to discuss it.”

Isla also joked she didn’t know who the baby daddy was: “I’m doing DNA tests with the casts of Hot Rod and also Wedding Crashers, so hopefully I’ll find out for sure.”

It was Andy Samberg!

Sacha Baron Cohen and his pregnant fiancee Isla Fisher (due any day now) attend a local synagogue to celebrate Yom Kippur (The Day of Atonement) on Saturday in Los Angeles.

Sacha, 35, was born in London to an Orthodox Jewish family. Isla, 31, has reportedly converted to Orthodox Judaism in advance of her marriage to Sacha. Their wedding date has yet to be announced.

Isla also recently signed on to star as the title role of Rebecca Bloomwood in the upcoming romantic comedy Confessions of a Shopaholic. The film tells the story of a college grad who lands a job as a financial journalist in New York City to support where she nurtures her shopping addiction. It’s based on the novel with the same name by Sophie Kinsella. Production will begin in January.

Actor pals David Arquette and Sacha Baron Cohen play a game of pick-up basketball in Hollywood on Saturday.

According to one spywitness, Sacha was a great rebounder and David played good defense. And apparently every time Sacha scored a point, he hand gestured his signature dip snap and shouted at his opponents, “BIG UP YASELF!”

Sacha and pregnant fiancee Isla Fisher did attend a beach party BBQ last weekend at David and Courtney Cox-Arquette’s Malibu beach home (Jennifer Aniston was also there).

BOOYAKASHA!!!
