has reportedly rekindled his relationship with estranged wife Téa Leoni
. The pair - who have daughter Madelaine, 15, and son Kyd, 12, together - were spotted looking like lovestruck teenagers during a recent family holiday to Fire Island in New York last month. An eyewitness told Star
magazine: ''They were smiling and cuddling up with one another. They walked hand in hand and shared a kiss.''
The insider said their children seemed to be thrilled that they are back together, adding: ''They seemed like the perfect family.'' The X-Files
star married the actress in 1997 but separated in 2008, with Duchovny checking into a
facility to be treated for sex addiction the same year. Speaking about his sex addiction, Duchovny, 53, previously said: ''Sex, to me, means I can forget myself. It's just the moment. I heard that skiing is even better than sex. It could be possible - but I'm not a skier.''
