Is Drew Barrymore in the middle of a love triangle?

The actress and director Spike Jonze, who were first linked about four months ago, were spotted Tuesday at music venue El Rey Theatre, where they caught a show by the Klaxons and were seen cuddling and kissing in a VIP booth.

Barrymore was seen playfully tracing Jonze's moustache before smooching him for a good 10 seconds, according to an audience member.

But only last week, Barrymore, 32, was seen in New York getting cozy with Scrubs star Zach Braff.

Barrymore and Braff first sparked romance rumors in February, when they bonded at a Saturday Night Live afterparty. Then, on June 30, the rumors were revived with they stepped out in N.Y.C., hitting the dance floor at Beauty Bar.

"There was a moment when they kissed and it seemed almost blissful," an onlooker tells PEOPLE.

Days later, on July 3, Braff, 32 – who is spending the summer in Manhattan and recently wrote on his blog that he's "dating" – wrapped his arm around Barrymore as they strolled through SoHo. "It was definitely romantic," says a witness.

Reps for Barrymore and Braff had no comment. A rep for Jonze said Wednesday: "We don't comment on our clients personal lives."
