Sir Richard Branson has apologised after being accused of rubbing his face in the breasts of one of Joss Stone’s backing singers.

Antonia Jenae, 44, reportedly alleged that the billionaire “motorboated” her - putting his face in her breasts, shaking it and blowing like a boat engine.

She told The Sun: “His behaviour was disgusting. I feel like it was sexual assault.”

Ms Jenae claimed he also pleaded with her to go topless at a 2010 party on Necker Island in the British Virgin Islands after she and Stone had played a gig.

A spokesman said the Virgin boss had no memory of the alleged incident and there was no intention to offend, adding: “Richard apologises if anyone felt that way.”

Branson’s spokesman told Mirror Online that the Virgin boss had no memory of the alleged incident but noted that everyone had appeared to have a good time.

The spokesman said there would never have been any intention to offend anyone.

“Richard apologises if anyone felt that way,” the spokesman said.

Mrs Jenae reportedly claims she and Stone recorded a video afterwards capturing their shock at the incident.

Stone’s representatives reportedly declined to comment on the claims.

A day later Mrs Jenae flew on the billionaire’s jet with him and his wife Joan on what she says was an awakward flight.

The full statement from a Virgin Management spokesman reads: “Joss Stone, members of her family and her band were invited to Necker Island in June 2010. Everyone appeared to enjoy their time on the island.

"Richard has no recollection of this matter and 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 in any way and Richard apologises if anyone felt that way during their time on the island.”

Virgin also issued a statement from Stone's father, Richard Stoker, who was on the island at the time.

“Joss and the group had a wonderful afternoon on Necker Island, everybody entered into the party spirit and it was wonderful getting to know Richard and his family," he said.
