Washington, Sept 20 : Actress Drew Barrymore has fuelled rumours that she and Justin Long are a couple after being caught “making out” in public.

The couple was first linked when they were spotted in August, enjoying a weekend long PDA-fest at the Austin City Limits Music Festival in Texas.

A source revealed, “they were making out all over the place,” in the festival.

They were even caught smooching through a bash for Arcade Fire at the Belvedere Music Lounge on Sept 15 and the next night, they got cozy at a Wilco show.

“They were like kids in love,” Us quoted an onlooker, as saying.

At the L.A. set of their comedy where the pair has yet to share a scene, Barrymore sent text messaged to Long during breaks.

“She’s really into him,” a source said.

“But she was never monogamous,” a pal said. (With inputs from ANI)
