Drew Barrymore and Justin Long are getting serious

Looks like Drew Barrymore and "Mac guy" Justin Long are getting serious. The He's Just Not That Into You costars spent Thanksgiving with Long's family in his hometown of Fairfield, Conn.

Then, on Friday, the couple kicked back at the nearby Southport Brewing Company, where they shared some late-night cocktails, laughs and, yes, a smattering of smooches. "They started out in the bar area and then moved to a booth, where they sat next to each other and kissed and hugged," one eyewitness tells PEOPLE. Adds another patron: "Drew and Justin were adorable."

Long also recently filed a new entry on his official Web site, saying he was headed to the East coast to see his "girlfriend" and spend Thanksgiving with "the fam." He also raved about Flower Films, Barrymore's production company.

The two were first spotted together in late summer. Before that, Barrymore had been linked to Scrubs star Zach Braff and director Spike Jonze.
