Pictures: Jennifer Lopez Celebrates Birthday With Casper Smart

International star Jennifer Lopez celebrated her 43rd birthday with her boyfriend Casper Smart in a stunning outfit.
The 25-year-old boy was holding Jennifer's hand when the two stepped out of the hotel and were getting ready to go to a fancy rastaurant to spend the evening.
The singer showed off her slim figure in a pair of skinny leather trousers and a simple white shirt, and Casper wearing a navy blue suit.
A source said that Casper has even planned for an after party on a Yacht at midnight for the two lovers.
It's noteworthy that Jennifer will not be an American Idol judge for next year, and Mariah Carey will replace her with an 18 million deal.
