It's no secret that Jessica is a big football fan -- her fiance is NFL tight end Eric Johnson -- so it came as no surprise when she enthusiastically tweeted a photo of herself at the big game.
"Fun at the Super Bowl!" she wrote with the pic that also showed the field at Lucas Oil Stadium. She later added that she had "stayed up past her bedtime."
Jessica is due to have her first child this spring and is expected to launch her own maternity line soon. The singer has also signed on to be the next spokesperson for Weight Watchers following the birth of her baby.
