Who's been a naughty boy then? Professional party-goer Calum Best stepped out at London hotspot Funky Buddha last night with a black eye.

Ladies man Calum kept mum on exactly how the mishap occurred, but there's no doubt a long line of people who would have gladly thrown the offending punch.

The 26-year-old overphotographed son of late football legend George Best is notorious for his heart-breaker ways - including actress Lindsay Lohan's - so maybe a wronged woman was responsible.

It's a mystery: Professional playboy Calum Best stepped out in London last night, at hotspot Funky Buddha, with a very noticeable black eye

Lothario: Calum with ex Lindsay Lohan in New York last year

Last year he was seen frolicking on the beach in the Bahamas with the 21-year-old actress.

However, the Celebrity Love Island contestant was caught just days later collecting phone numbers from models while at a New York club.

He has insisted that his wild days are over, but the black eye would suggest otherwise.

He said: "I don't mind the playboy image but I'm now at a point where I want to be taken seriously."

Calum has been linked to model Kimberley Stewart, Jodie Marsh and Girls Aloud bombshell Sarah Harding, among others.

Calum was seen at Funky Buddha along with most of the Chelsea football team who were celebrating last night's Champion's League win over Turkey's Fernerbahce.

Lampard, Michael Ballack, Shaun Wright-Phillips, Ricardo Calvalho and Joe Cole donned their designer jeans for a night on the tiles after their 2-0 win over Fenerbahce.

Though a notable absentee from the party was Ashley Cole, whom wife Cheryl is clearly keeping a tight rein on following his transgressions.
