Los Angeles: Popstar Jennifer Lopez`s dancer boyfriend Casper Smart threw a surprise party for the singer on a yacht docking in a harbour in uptown Manhattan.

The singer-actress took a break from her tour with Enrique Iglesias to celebrate her 43th birthday with her toyboy Smart, reported Ace Showbiz.

The 25-year-old covered Lopez`s eyes with a scarf when they arrived at the spot. The former `American Idol` judge, who was born on July 24, 1969, looked genuinely surprised when Smart uncovered her eyes.

The yacht had been decorated with black and white balloons and was crowded with guests supposedly comprising of family and close friends.
