Professor Green is expecting his friends to ''ruin'' him with ''drugs and prostitutes'' on his stag night.
The rapper - who grew up on a tough council estate in East London - is to tie the knot with 'Made in Chelsea' star Millie Mackintosh later this year and he is expecting his send off as a bachelor to either be a crazy night of debauchery, or ''s**t'' because his pals will forget to arrange anything for him.
He said: ''Well I don't get to plan it, do I? But my mates are f***ing reprobates so they'll either just not plan anything and it'll be s**t, or they'll absolutely ruin me with drugs and prostitutes. That's what every good stag do is made of.''
The 29-year-old star - whose real name is Stephen Manderson - has already chosen his outfit for the nuptials, but he is undecided as to whether he should shave off his facial hair or not, despite his 23-year-old fiancée's mother not being keen on his rugged look.
Speaking to Nuts magazine, he added: ''I had my suit fitting the other day. I haven't decided whether to shave or not yet.
''Millie likes my attempt at facial hair, but Millie's mum hates it. It depends on how I feel on the day.''
