Jennifer Lopez danced around a private yacht on Sunday to celebrate her 42nd birthday. The singer, who announced her split from husband Marc Anthony over a week ago, didn't look to be mourning her failed relationship as much as trying to move past it. The hot mom donned a matching bikini and head scarf as she showed off her toned tummy on the high seas.

The American Idol judge wore a high-end Emilio Pucci bikini and head scarf, paired with a white maxi skirt, as she shimmied around the boat.

She was also seen lounging with pals aboard the Never Say Never yacht, enjoying some fruity cocktails.

"Thank you all of my Lovers for the birthday wishes! I'm having an amazing day surrounded by family and friends," Jennifer Tweeted yesterday.
