UPDATED: The singer was taken by ambulance to Bellevue Hospital after being assaulted late Sunday.

Singer Gavin DeGraw was rushed to a New York City hospital late Sunday after being assaulted, his rep confirmed to The Hollywood Reporter.

DeGraw, best known for his mid-2000s hit "I Don't Want to Be," was taken to the emergency room at Bellevue Hospital by ambulance after the attack.

His rep said DeGraw remains under observation but did not provide further information about the attack or his condition.

TMZ, which first reported the incident, claimed that the singer, who is a New York resident, was assaulted by multiple attackers.

Meanwhile, the New York Post cites sources who say that DeGraw had been drinking with a group of friends before leaving them behind and was assaulted sometime between 3:50 a.m. and 4:20 a.m. at 6th Street and 1st Avenue.

His nose was broken, and he also suffered cuts on his face as a result of the attack, which the sources do not believe was a robbery. Afterward, he kept walking and was then hit by a taxi, though not seriously, according to the Post.

DeGraw is currently on tour with Maroon 5 and Train, with a show scheduled for Tuesday in Saratoga Springs, N.Y., and another Friday at Jones Beach Theater.

His "I Don't Want to Be" also serves as the theme song of One Tree Hill. [Watch the video below.] It's off his 2003 debut album, Chariot.

Other singles have included "Chariot," "Follow Through" and "In Love With a Girl."

He is set to release his next album, Sweeter, on Sept. 20.
