Singer Gavin DeGraw -- best known for his smash hit song I Don't Want To Be -- remains hospitalized in New York City with a broken nose after he was attacked Sunday by a group of thugs on the street, RadarOnline.com has learned.

New York police spokesman Lieutenant John Grimpel said it was not clear what led to DeGraw's attack in the city's East Village, or how many individuals assaulted the 34-year-old singer.

DeGraw's rep issued a statement saying: "Gavin DeGraw was assaulted late Sunday night and taken to the emergency room at Bellevue Hospital by ambulance. He is currently under observation."

The man that struck Paris Hilton's boyfriend Cy Waits outside of the Van Nuys, Ca. courthouse Wednesday has been sentenced to 200 days in jail, RadarOnline is reporting.

James Rainford pleaded "no contest" to misdemeanor battery; neither Hilton or Waits were hurt in the attack.

Rainford had previously been arrested for trespassing into the exclusive gated community where Hilton owns a multimillion dollar mansion.  After his arrest yesterday, he told cops he "loved" Paris and had been given permission by her father to marry her.

Paris and Cy appeared in court Wednesday to testify against Nathan Parada, who is accused of felony burglary after being arrested at Hilton's Beverly Hills mansion last October. Parada had two knives in his possession and was trying to break into the house as the couple slept.
