Some of Malibu's brightest fireworks came in the middle of the day, thanks to a wild prank from Jim Carrey.

Carrey and girlfriend Jenny McCarthy were strolling down the beach on the Fourth of July with paparazzi snapping their every step. McCarthy wore a stunning black haltertop swimsuit.

The couple disappeared for several minutes into a beach hut. When they emerged, McCarthy was in a stunning blue sundress while Carrey had taken her black bathing suit for himself.

McCarthy tried to keep a straight face while the paparazzi continued snapping and beachgoers stopped in amazement.
