Los Angeles, March 15: Pop star Britney Spears reportedly suffered a panic attack during an Oscar party.

The “Perfume” singer, who had a public breakdown in 2007, reportedly felt overwhelmed at singer Elton John's AIDS Foundation Oscar-viewing party at West Hollywood Park, and made a quick dash to the exit after just minutes of being in the room.

''Britney was excited when she first went to the party but moments later she was fazed about being at such an over-crowded event,” contactmusic.com quoted a source as saying.

''She started to break out in a sweat and become short of breath, it was like she was having a panic attack,” the source added
