Pink and motocross racer Carey Hart have separated after two years of marriage.

"This decision was made by best friends with a huge amount of love and respect for one another," Pink's representative, Michele Schweitzer, said Tuesday in a statement. "While the marriage is over, their friendship has never been stronger."

Pink, whose real name is Alecia Moore, met Hart at the 2001 X Games in Las Vegas and proposed to him four years later during a race in Mammoth Lakes, Calif. They were married Jan. 7, 2006, in Costa Rica.

Pink, 28, won a Grammy for best female rock vocal performance for her song "Trouble" in 2003. Her hits include "Get the Party Started," "Stupid Girls" and "Don't Let Me Get Me."
