Even with the fabled excesses of the movie business, it's unheard of for a co-star of a film to spend any money at its afterparty.

After all, such a bash is the last chance for the cast and crew to milk the film's budget for free food and booze.

An expensive night: 50 Cent leaves Alto club

But not every actor has the disposable income of American hip hop star 50 Cent, who took bar tabs to a whole new level last night after dropping £75,000 over the bar at the afterparty of Dead Man Running at Alto club in Soho.

The 33-year-old rapper hired the entire VIP area for his entourage, friends and film colleagues.

And he's not even the star — being officially billed behind Tamer Hassan, Danny Dyer... and Brenda Blethyn.

Our spy told us: “When he arrived at the club it was mayhem. The area was cleared for him and security ushered him straight through. On his table were bottles of champagne but he wanted a magnum bottle of Ace Of Spades champagne.

“You could tell that he was loving all the attention as people were trying to take pictures on their phones and were shouting his name.”

50 Cent, real name Curtis Jackson but also known as “Fiddy”, plays a gangster and loan shark called Mr Thigo in the film, a character not a long way away from his real-life past.

Moments after he arrived, security was left in a state of panic when a horde of girls tried to break into the VIP area in a desperate bid to meet the American star.

Out of the hundreds that were pushing against the ropes, 15 girls managed to get past security and he allowed them to sit at his table for the remainder of the night.

Our spy added: “50 has never been one to turn a lady away, so when he saw that a few ladies had made it into his VIP area he allowed them to sit with him.

“They were drinking his champagne from the bottle and they were obviously in their element. 50 was chatting away to them and the girls were giggling and dancing around his table.”

He left the club alone just after 3am.
