A baby Borat is born: Isla Fisher and Sacha Baron Cohen have welcomed their first child, according to reports in Australia
No further details were available. Reps for both stars had no comment.
Fisher's pregnancy was first reported in June
. The following month
she said, "I haven't got any plans to jump back into [work after the birth]."
Both Cohen, 36, and Fisher, 31, began their careers overseas. Cohen, who is best known for his controversial comedy
, Borat: Cultural Learnings of America for Make Benefit Glorious Nation of Kazakhstan
, originally rose to fame on British TV as the wannabe rapper Ali G, and became familiar to American audiences in 2003, when HBO began airing his Da Ali G Show
Fisher, who was raised in Australia, kicked off her acting career in the mid-'90s on the Aussie soap opera Home & Away
, but is better known internationally as Vince Vaughn's hyperactive love interest in Wedding Crashers
Fisher's former Home & Away
costar, Melissa George, told PEOPLE this week that Fisher will make a wonderful mother. "She's the kindest, most beautiful woman. Like extraordinary, this girl. And she's got great humor, an amazing sort of temperament."
As for the sense of humor the baby might have, George said, "It'll be a riot. How could it not?"
Fisher told a British newspaper in 2005: "Sacha makes me laugh more than anyone," but this year admitted there are perils
to maintaining the relationship.
"Instead of 'Hey, Honey, did you pick up the dry cleaning?,' it was 'Did you get beaten up? Are you getting sued? Is there a warrant out for your arrest?' " she said, referring to Cohen's work on Borat.
