J-Lo sneaks up on A-Rod with birthday surprise

It can be a drag to work on your birthday, but not if you get a surprise visit from Jennifer Lopez. 

The superstar surprised her fiance Alex Rodriguez in the broadcast booth Sunday night. 

The former slugger was working the Yankees vs. Red Sox game in Boston when J-Lo and A-Rod's daughters brought a cake to celebrate his 44th birthday. 

Lopez just celebrated her 50th birthday last week.
