He might be the richest man in hip-hop but even rapper Jay-Z sometimes has problems getting into nightclubs.Beyonce’s fiance came a cropper when he turned up to swanky London venue Kabaret’s Prophecy with his 15-strong entourage.

They asked for a table – and were turned away, after being told the club was full.

“Jaz-Z turned up just before 2am,” a source told the Daily Mirror.

“He was keen to party and rushed down the stairs to look for a table.

“But he was told there was no way he and his party could be seated as the club was heaving. We were stunned.”

But instead of throwing a star strop and demanding to be seated, Jay-Z calmly left, according to the source.

Jay-Z with fiancee Beyonce“He was a real gent about it. He left, saying ‘This place rocks – I’ll be back’.”

The multi-millionaire rapper had a run of bad luck when he arrived in the capital yesterday, to pick up a GQ Man Of The Year Award.

He was due at London’s Cafe De Paris last night to see one of his protegees, Teairra Mari, perform.

But fans waiting for a glimpse of him were disappointed when he showed up late and refused to mingle with them.

From there, he went on to attend a party for his Rocawear clothing line.

But it took him ages to get in after a problem with his keys – and it was eventually 1am before he showed up at the party.
