Jennifer Lopez was treated to an early birthday surprise on Thursday (23Jul09) when she was presented with a big cake by the cast and crew of her new movie THE BACK-UP PLAN.
The lovely Latina - who turned 40 on Friday (24Jul09) - has been busy shooting the movie in New York City, but the crew hadn't forgotten about the singer/actress' big day.
After filming had wrapped for the night, they brought out a large chocolate treat featuring a photo of the star to kickstart her 40th birthday celebrations.
The icing on the cake read: "Jennifer... thanks for being our Plan A! You're the best. And... happy birthday!"
Lopez's husband Marc Anthony was also on hand to get the party started and gave the birthday girl a big kiss before toasting her milestone with champagne, reports Eonline.com.
