Jennifer Lopez celebrates her 43rd birthday on a boat!

Our Splash cameras caught the singer with boyfriend Casper Smart, as they boarded a super yacht in New York City.

Jennifer as always, looked dashing in a skin tight long sleeved red dress.

Casper looked elegant in glasses, and a maroon sports coat with black trousers.

With cool Casper by her side, we bet she had an amazing day!

Happy Birthday Jennifer!
