Paris's embarrassing lip-syncing exposure at b'day

New Delhi (ANI): American socialite Paris Hilton was left a little red faced after she was exposed to have been lip-syncing her hit song ''Stars Are Blind'' at her birthday party on March 7.

The incident happened at the Body English nightclub at the Hard Rock Hotel and Casino when Hilton"s new boyfriend Doug Reinhardt took the microphone off her, only for the song to continue playing, reports China Daily.

“Paris was really going all-out to impress Doug until he took the mic off her and the singing just carried on. Everyone in the club thought it was hilarious," a source said. Hilton has already celebrated her birthday in New York, Los Angeles and Tokyo.
