Washington, January 28 : Brad Pitt was reportedly left red-faced after he was asked to hand over his beer bottle as he was getting into a car.

The `Curious Case of Benjamin Button' star was recently spotted attending a Grey Goose SAG after-party with partner Angelina Jolie.

According to a Pop Tarts eyewitness, the actor did not realise he was carrying the beer as he headed towards his vehicle, reports Fox News.

And just as he was seen tiptoeing off the back door, organisers requested Pitt to lay down the bottle, to which the embarrassed celebrity obliged.

Pitt was later spotted being driven away from the star-studded evening, which also saw other guests such as Katie Holmes and Sean Penn. (ANI)
