Billionaire Richard Branson is now being accused of sexual harassment from an incident that happened on his Necker Island in 2010.

Singer Antonia Jenae alleges that Richard stuck his head between her breasts and “motorboated” them by blowing and making an engine noise. Antonia was a backup singer for Joss Stone at the time.

“He went ‘brrrrrr’ and just walked away. It was surreal, totally out of the blue. Joss and I were like, ‘What the hell was that?!’ Everyone was wondering why I wasn’t angry because I’m usually a firebrand. But I was just too shocked,” she wrote on Facebook.

She also said that Richard tried to get her to show him her breasts and walk around topless.

“Richard has no recollection of this matter. Neither do his family and friends who were with him at the time. There would never have been any intention to offend or make anyone feel uncomfortable. Richard apologizes if anyone felt that way,” a spokesperson said.
