A source says, "They have definitely split up, but it is very complicated because their kids are very close. They still spend a lot of time together."
Prior to her most recent relationship, O'Donnell was married to former Nickelodeon executive Kelli Carpenter from 2004 to 2007, although O'Donnell waited until 2009 to go public with their split. O'Donnell and Carpenter have remained friendly co-parents for the sake of their four children, with the TV star saying of the breakup, "We're a family, we remain a family ... Kelli and I love each other very much, and we are working on our issues."
The 48-year-old comedian is reportedly seeking a similar level of civility in her split with Kachtick-Anders, who recently moved herself and her children into a new home.
