After attending a friend's wedding in Dallas, Jessica Simpson and beau Tony Romo headed to Al Biernat's steakhouse to celebrate another pal's birthday after the reception.

The couple had a good time over dinner, and Simpson even signed autographs for young female fans who approached. "She was very gracious," says the staffer.
