Will.i.am was left fuming after being kicked out of a first class lounge at an airport yesterday.

The Voice UK coach took to Twitter to hit out at United Airlines after reportedly being told to leave a VIP lounge because staff thought he had a fake membership card.

Cheryl Cole’s BFF posted on Twitter, ”#unitedAIRLINES is the worse. Im a member & I have my card to prove it. but they tell me my card is fake & kick me out the lounge #ouch (sic).”

He added, ”Ha ha ha I got kick out the club…#unitedCLUBsucks…(sic)”, with a photograph of the ‘Global First Lounge’ sign as he stood outside.

While it’s unclear what airport the star was flying from, he had earlier tweeted that was planning on visiting his good friend Puff Daddy in Washington D.C for his speech at Howard University that day.

”I fly so much.. a business should know who their customers are… its okay im making this my lounge,” the peeved celebrity posted, along with a photograph of a chair in the corner of the airport.

And he still wasn’t done…

Later on, when a pilot asked for his autograph, he tweeted, ”I get kicked out of the @united lounge because they say I’m not a member.. oh well.. & then the @united pilot asks me to take a selfie #WTF. (sic).”
