Actress Kelly Rowan, known for her role on The O.C., has split from her fiance, David Thomson, just weeks after giving birth to their baby girl, according to the New York Daily News.

Rowan, 43, gave birth to their daughter on April 28 in L.A.

Thomson, Canada's richest man, has three children from a previous marriage.

The couple had been staying out of the limelight in Canada because Thomson is "horrified of any publicity," the New York Post reported in March.

The couple had been together since 2006.
