Britney Spears has "willingly" entered a 72-hour psychiatric hold at UCLA Medical Center.

In a scene reminiscent of the Jan. 4 scene outside the 26-year-old singer's home, Spears was escorted by police in an ambulance to the hospital while paparazzi swarmed. This time, however, the motorcade was planned and "worked out perfectly," according to a source.

"She'll be in there for at least 72 hours getting evaluated," the source says. "She's more comfortable this time."
