More than 100 guests attended the wedding, which was held on the beach at the Four Seasons resort, People magazine reported.
"We just love the beach, so we knew we wanted it to be at the beach," the 26-year-old rock star told the magazine.
Pink, whose real name is Alecia Moore, met Hart at the 2001 X Games in Las Vegas and proposed to him last summer during a race in Mammoth Lakes, Calif.
In 2002, Pink won a Grammy for best pop collaboration with vocals for her cover of "Lady Marmalade" with Lil' Kim, Mya and Christina Aguilera. She will star in the upcoming horror film "Catacombs."
Hart, 30, appeared on the fifth season of the reality show "The Surreal Life."
This is the first marriage for the couple.
