Britney Spears suffered a "panic attack" at an Oscars party.
The 'Perfume' singer, who had a public breakdown in 2007, reportedly felt overwhelmed at Sir 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.
A source said: "Britney was excited when she first went to the party but moments later she was fazed about being at such an over-crowded event.
"She started to break out in a sweat and become short of breath, it was like she was having a panic attack."
The 32-year-old star shaved her head during a meltdown seven years ago and was photographed attacking a paparrazo's car with an umbrella.
Her breakdown led to her losing custody of her sons Sean Preston, eight, and Jayden James, seven, to ex-husband Kevin Federline, and the singer, who suffers from bipolar disorder, still has issues being at parties.
The source added to Closer magazine: "Britney still finds large crowds nerve-wracking and doesn't feel comfortable at showbiz events.
"The chaos of the red carpet and all the unfamiliar faces is very daunting. She manages to block out the crowd and put on an act when she's on stage, but it's harder when she's socialising."
