Kelly Rutherford & Ex -- Ceasefire for Baby

4/26/2010 1:15 PM PDT
After one of the nastiest splits in the history of Hollywood, "Gossip Girl" star Kelly Rutherford called a temporary truce with her estranged husband Daniel Giersch this weekend -- so baby daddy could spend some time with their 2 kids.

Earlier this month, Kelly dropped the restraining order against Daniel -- but yesterday in L.A., the two agreed to act like civil, peace-loving people so Kelly could drop off the kids.

Baby steps.
