Stop us if you've seen this one before. In a repeat performance, on-again, off-again power couple David Duchovny and Tea Leoni have put their 14-year marriage on the back burner yet again. And it's not the first time. Back in 2008, the couple went on hiatus after the 50-year-old Golden Globe winner entered rehab for sex addiction. Duchovny and the 45-year-old beauty later rekindled their romance and reconciled. Now, it appears things have once again gotten off track. TMZ is reporting that the duo are "taking time apart." However, they have yet to decide whether or not to divorce. They have two children together -- 12-year-old Madelaine and 9-year-old Kyd.
