“They’re back together,” a source tells PEOPLE of the pair, who spent all of Sunday together at Wilson’s Malibu home. Also there: Hudson’s 5-year-old son Ryder.
Hudson, 29, and Wilson, 40, most recently re-united in Feb. 2008, when they appeared cozy at last year’s Academy Awards. The two continued to hang out for several months – even celebrating Hudson’s birthday in Miami – before breaking up again in May 2008.
“It was a pretty bad breakup,” a friend of Wilson’s told PEOPLE at the time. “Owen said it was a tough one. He definitely doesn’t want to dwell on it. He wants to put it behind him.”
The two began dating originally in Sept. 2006, after filming You, Me and Dupree together. They later split in June 2007, but remained “friends” at the time, a source told PEOPLE.
