Pink and her husband of two years, motocross racer Carey Hart, are throwing in the towel, People.com reported Tuesday.

“This decision was made by best friends with a huge amount of love and respect for one another. While the marriage is over, their friendship has never been stronger,” Michele Schweitzer, the pop singer’s publicist, told the magazine.

Pink, whose real name is Alecia Moore, married Hart in Costa Rica on January 7, 2006.

The 28-year-old singer proposed to Hart while he was mid-race in Mammoth Lakes, Calif. the previous June, according to the Associated Press. The couple had met at the 2001 X Games.

In recent months, Moore and Hart, 32, each denied their marriage was on the rocks. Saturday, TMZ reported seeing Hart with another woman at the Tabu Ultra Lounge at MGM in Las Vegas.

Diverging career paths may have caused the split, according to TMZ, which also reported that Hart will open a nightclub called Wasted Space at the Hard Rock Caf© in Vegas.

Meanwhile, one-time Grammy winner Pink is back in the studio, solo.
