British rapper Professor Green stepped behind the bar to serve drinks to guests at the opening of his new London pub this week (ends08Sep13).

The hip-hop star, real name Stephen Manderson, launched Ink in London's famous Leicester Square on Wednesday night (04Sep13) with a glitzy party ahead of the public opening on Thursday (05Sep13).

Manderson helped out the venue's staff throughout the evening and even handed out drinks to guests, according to Britain's The Sun.

He is also adamant he will remain a hands-on boss now the pub is open, telling reporters, "We're open seven nights a week so I am going to be here a lot. I have to be. I'm meticulous, so I can't just sit and watch."

Guests at the party included Emeli Sande, Diana Vickers, Wretch 32 and Carl Barat, as well as Professor Green's reality Tv star fiancee Millie MACkintosh. Reports suggest the couple will walk down the aisle next week (beg09Sep13).
