Omarion pulls out of DSTRKT nightclub appearance
Omarion pulled out of a planned appearance at DSTRKT nightclub.
The musician was set to perform on Friday night at the London venue, but tweeted to say he would not attend.
DSTRKT has denied allegations it turned women away from its doors for being "overweight" and "too dark".
A protest was held outside the club in the centre of the capital, after a group of women said two of them were not allowed in because of their race and appearance.
The management said: "DSTRKT restaurant and club has launched a thorough investigation into this alleged event and found that at no stage did any of the DSTRKT staff said to the women they were not to be allowed in on any the basis of their skin colour or size."
One of the women involved, Zalika Miller, says she "couldn't believe the amount of support" she and her friends had received on social media.
Omarion, whose real name is Omari Ishmael Grandberry, is best known as the lead singer of the band B2K. His new album, Reasons, is due out later this month.
DSTRKT had been promoting his appearance as recently as Friday afternoon.
On its website, DSTRKT says it has a long list of celebrity visitors, including Kim Kardashian, Jay Z and Rihanna.
Chris Brown's ex-girlfriend, model and actress Karrueche Tran, attended an event at DSTRKT on the night of the protests.
"It's unfortunate to hear about something like that, especially something that I'm part of," she told Newsbeat. "I'm half African-American too. I have god-sisters and family who have darker skin as well.
"I don't support any sort of discrimination. I love people for who they are."
Her event went ahead despite the protest and some people on social media calling for a boycott.
