Boxing champ Scott Welch has already exchanged blows with Hollywood heart throb Brad Pitt.

But last night, the former world title contender had to fight through the crowds as he attended the film premiere of Snatch.

The movie is the latest by Lock, Stock And Two Smoking Barrels director Guy Ritchie.

Scott, 32, of Old Fort Road, Shoreham, puts Pitt through his paces in the final fight scene of the film, which also stars ex-football hard man Vinnie Jones.

Yesterday he did not have the jitters about his acting debut being shown on the huge cinema screen.

Speaking before the premiere at the Odeon, in London's Leicester Square, Scott said: "I have met quite a few of the stars who are going already, so I'm not nervous."

The father-of-two attended the premire with his wife Maria while their children Thomas, five, and two-year-old Lily stayed at home with an auntie.

The couple were flanked by an array of glamourous guests including Pitt and his new wife, Friends star Jennifer Aniston, as well as new dad Guy Ritchie.

His girlfriend, pop idol Madonna, was expected to stay in Los Angeles and look after their two-week-old son Rocco.

Later Scott and Maria went on to celebrate with the stars at a post-premire party in a trendy London bar.

Scott said: "I'm used to meeting famous people through boxing and all the people involved with the film are just really nice guys."

While the former heavyweight champ, who retired from the ring last year, was laid back about mingling with the stars, his wife was thrilled at the prospect of chatting with Pitt.

Maria said: "He is a such a nice man and doesn't act like a celebrity at all. Last time I met him he was talking about how hard Scott had punched him."

Scott, who plays the toughest fighter in a London gang, spent two weeks on set with Pitt choreographing the film's final violent scene.

He got the part after the film crew phoned him out of the blue and invited him to audition for the gangster caper which revolves around a heist set in London's diamond district, Hatton Garden.

If Snatch is as successful as Lock, Stock And Two Smoking Barrels, which grossed £11.3 million, it could launch an acting career for Scott, who is currently in the construction industry.

But Maria said: "It was a lovely opportunity but I can't see him acting full-time."
