Tony Romo has presented his love, Jessica Simpson, with a six-carat diamond pendant as a Christmas gift.

“Jessica loves it, but she’s afraid to wear it because it’s a one-of-a-kind piece and very delicate,” one of the blonde’s friends spills to Star Mag.

“It was intended to be a good lickk charm that Jess could wear at the Cowboys’ playoff games…He’s hoping to turn Jessica into his Lady Luck-and perhaps make his way to the Super Bowl.”
