Jessica St. Clair is a mom!
The actress, who is known for her roles in Bridesmaids and the TV series Best Friends Forever, welcomed a baby girl with her husband Dan O'Brien.
Isobel Kelly O'Brien was born on Oct. 1 in Santa Monica, Calif., and weighed in at 9 lbs., 9 oz.
"Everyone is healthy, happy and doing great," St. Clair's rep tells E! News.
St. Clair is certainly following in the footsteps of her former Best Friends Forever costar and good buddy Lennon Parham. St. Clair and Parham married within one week of each other in July 2006 and Parham gave birth to a baby girl in April.
