It's official, actress Kate Beckinsale and her director husband Len Wiseman have called it quits.

The couple, married in May 2004 after meeting on the set of their 2003 film Underworld, have apparently been separated for months now.

A source told People magazine that the couple's conflicting schedules caused them to grow apart.

"They are still friendly and spend time together in L.A. when Kate is there," the source said.

The public began to figure things out when Len, 42, was seen out in L.A. with 24-year-old model CJ Franco, and without his wedding ring for the third time in two months.

Beckinsale, who's also 42, has been in Prague filming Underworld 5. The source added that Kate is "not dating and only focused on her daughter and work."

The couple did not have any children together, although he was apparently close to his stepdaughter.
