Wedding Planner costars Jennifer Lopez and Matthew McConaughey reunited on the shores of Malibu on Sunday morning.

The two were among the hundreds of participants at the annual Nautica Malibu Triathlon, which benefits Childrens Hospital of Los Angeles' Pediatric Cancer Research Program.

The 39-year-old singer/actress finished the half-mile ocean swim, 18-mile bike ride and four-mile run in 2 hours, 23 minutes and 28 seconds, according to People magazine.

Husband Marc Anthony cheered from the sidelines and escorted Lopez to the VIP area after she crossed the finish line.

J.Lo, who gave birth to twins Max and Emme in February, enlisted the help of trainer-to-the-stars Gunnar Peterson to prepare for her first triathlon.

Plenty of other stars turned out for the event, including Felicity Huffman, William H. Macy, Mark-Paul Gosselaar, Scott Foley, Monique Coleman, Jon Cryer, Anna Kournikova and The Bachelor Andy Baldwin.
