Gaga, 25, and Kinney, 30, were caught taking a stroll together in rural California. The lovers reportedly stayed at a beach house, which Kinney shares with three friends.
Mother Monster and the 'The Vampire Diaries' actor reportedly started hooking-up back in September after meeting on the set of Gaga's 'You and I' music video in July. The on-screen couple certainly steamed it up for the cameras, and have since developed a real-life romance!
The pair have reportedly been inseparable since that first hook up, but until now, have always left hotels and bars separately in a bid to keep their relationship private.
Gaga has refuses to speak publicly about the relationship, but told Katie Couric in an interview for a holiday TV special, "You know I don't talk about my love life, but I'm very happy." Reportedly Gaga and Kinney were recently spotted house hunting together in Kinney's Pennsylvania hometown. Looks like things are really getting serious for this handsome twosome!
