Drew Barrymore and Justin Long may be co-stars in the upcoming film He's Just Not That Into You, but that doesn't describe their relationship. The pair, who have been dating for a few weeks, seem to be headed for a full-fledged romance. An insider told Us Weekly, "She's really into him."

Last weekend, Drew and Justin were in Texas for the Austin City Limits Music Festival in Texas. They took in performance from several bands, including Arcade Fire and Wilco. One witness to their date at the Wilco show told Us, "They were like kids in love."

And the folks in the Wilco crowd weren't the only ones to view this hot new couple in a public display of affection. Another Festival-goer said, "They were making out all over the place" that weekend.

Will Drew's latest conquest be a flash in the pan like her flings with Zach Braff and Spike Jonze were? Maybe not. Said the insider for Us, "You can definitely tell that she likes him!"
