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.
Looks like these little ladies will be close buddies just like their moms!
Up next for the new mamas? Their upcoming USA show, Playing House, airs in 2014.
Congrats to the new family!
