Lady Gaga dating her 'You And I' boyfriend!

London, Sept 9 (ANI): Lady Gaga is apparently dating her 'You and I' co-star Taylor Kinney.

The 25-year-old singer was spotted getting cosy with model and 'Vampire Diaries' star Kinney, 30, who played her boyfriend in 'You And I'.

RadarOnline reported that the two met on the set in July and have been dating since.

"It was just casual at first, but things are getting pretty hot and heavy," the Daily Mail quoted a source as telling the website.

They have been seen together on three consecutive days, starting with drinks at seaside bar, The Sneak Joint in Mission Viejo, California, where Kinney lives, on Sunday.

A patron said they were drinking shots of Johnny Walker.

"I couldn't tell it was her at first," the patron said.

"It just looked like some hot couple making out, but then I realized it was Lady Gaga. Everyone went nuts. She was so sweet too-she even signed some autographs," the patron added.

The next day the pair was spotted holding hands while walking along Mission Boulevard.

And on Tuesday they were seen at the beach. (ANI)
