Drew Barrymore has fueled rumors she is dating her movie co-star Justin Long after the pair was spotted kissing over the weekend. The star, 32, enjoyed a passionate break with fellow actor Long, 29, at the Austin City Limits Music Festival in Texas, according to reports.

A source tells Us magazine, "They were making out all over the place. They were like kids in love."

The couple star together in the upcoming movie adaptation of the best-selling love guide, "He's Just Not That Into You."

Barrymore has been linked to a series of men since splitting from Strokes drummer Fabrizio Moretti in January, including Scrubs star Zach Braff and director Spike Jonze.
