AceShowbiz - Eminem's representative has denied claims the rapper swore at fans at the launch of his new clothing range.

The "Lose Yourself" rapper has collaborated with fashion label Rag & Bone on a capsule collection celebrating the end of his European "Revival" Tour and launched the line at a pop-up store in Carnaby Street, London, on Saturday, July 14.

According to editors at British newspaper the Daily Star fans were reportedly left seething after the "Not Afraid" hitmaker turned up for a matter of minutes and allegedly flipped the bird as he left.

Fans reportedly told the publication they had been left feeling "cheated and lied to" after they failed to get face time with the rapper.

"It was just (a) disgusting exploitation of loyal fans," one event-goer reportedly shared. "All Eminem did was turn up for a few seconds, pose for a photo and then give us all the fingers.

"Turning up for a few seconds with his bodyguards pushing people all over the place, then insulting us before he leaves - it was vile," the fan added.

However, a spokesman for the star has since insisted the claims are false.

"This story is not true and we will be following this up with the Daily Star as soon as possible and will be taking action if necessary," they told editors at WENN. "He was not confirmed or advertised to appear at the store at any point."

Eminem advertised the event on his official Twitter account last week, inviting fans to visit the store for a first look at the collection, which features three slogan T-shirts and a hoodie ranging in price from $95 (£72) to $250 (£190).

Meanwhile, bosses at Twickenham Stadium, U.K, were forced to apologise after a bag collection system descended into chaos following the rapper's Saturday night gig. Fans allegedly faced a two-hour wait to retrieve their belongings and risked being trampled on after thousands of bags were "dumped" on the floor by security.

"On the night there was a limited bag drop facility available operated by the promoter. Unfortunately this did not meet our usual standards. We'd like to apologise to all those who were impacted," a spokesperson for the venue told editors at NME.
