Pregnant Gossip Girl actress Kelly Rutherford and her husband of two years, German entrepreneur Daniel Giersch, are calling it quits.
Rutherford, 40, who is three months pregnant, filed for divorce on Dec. 30, citing "irreconcilable differences," according to papers obtained by PEOPLE.
Giersch filed for legal separation the same day, a source tells PEOPLE.
Giersch and Rutherford, who is expected on the Gossip set in New York Tuesday, also have a 2-year-old son, Hermes.
This is Rutherford's second marriage.
