Barrymore hooks up with Westwick

Drew Barrymore has sparked new romance rumours after she was spotted smooching 'Gossip Girl' star Ed Westwick at a recent Kings of Leon concert in New York.

Reports suggest the pair hooked up for a "full-on make-out session" at the band's Webster Hall show on Tuesday night, before heading off to a nearby bar together.

An eyewitness tells UsWeekly.com: "Drew was hanging all over Ed. There was definite chemistry."

Sources claim it's the second time newly-single Barrymore, 33, has enjoyed the company of the 21-year-old British TV star.

The pair also spent Saturday night together, at another New York hotspot with actress Ellen Page and Into the Wild star Emile Hirsch.

Barrymore recently split from boyfriend Justin Long.
