Jessica St. Clair following best pal into motherhood

Bridesmaids star Jessica St. Clair is pregnant with a baby girl.

The 35 year old and her husband Dan O'Brien will become parents on 1 October (13) - less than six months after her best friend, actress Lennon Parham, gave birth to a daughter named Saraya. The tot was born on 21 April (13), reports People.com.

Motherhood isn't the first life experience the pals have gone through together - Parham wed Javier Guzman, in July, 2006, a week before St. Clair exchanged vows with O'Brien.

They have also enjoyed a close working relationship, co-creating and co-starring in TV comedy Best Friends Forever, but the show was cancelled last year (12) after the first season.
