Introducing a new girlfriend to the family over the holidays is a sure sign things are getting serious. "Mac Guy" Justin Long brought his new girlfriend, Drew Barrymore, to meet the folks for Thanksgiving in his hometown of Fairfield, Conn. The couple, who met while filming He's Just Not That Into You, haven't kept it a secret that they're dating, often being spotted smooching while out and about. Thanksgiving weekend was no exception, as the two reportedly shared cocktails and kisses at the Southport Brewing Company on Friday night. Justin recently posted a blog on his web site saying he was heading to the East Coast to see his "girlfriend" and spend Thanksgiving with "the fam." We're sure Drew made a good impression!
