Funny couple Sacha Baron Cohen and Isla Fisher welcomed

their first child last week and sources have exclusively confirmed to OK! that

the duo have named their new baby girl Olive.

Olive made her last Wednesday, Oct. 17, in Los Angeles, but Sacha, 36, and Isla, 31,

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.
