Rihanna's bodyguard was reportedly involved in a physical altercation with the paparazzi.

A photographer got too close to the singer while she was in London on Sunday night (24.06.12) only to be punched by one of her bodyguards, according to website TMZ.com.

It remains unclear if the photographer was knocked out by the hit.

She has been working on new material during her stay in the English capital city.

It was recently claimed that Chris Brown feels ''really sorry'' for the people who were injured in his fight with Drake.

The 23-year-old singer was involved in a brawl with Drake at a nightclub in New York on June 14 and while he wishes to pass on his regret about the incident - in which sports star Tony Parker sustained an injury to his eye - he claims he did not start it.

A source said: ''Chris is really sorry and feels bad for the people who were injured at the club when all that s**t went down and wishes he could apologise to everyone that was injured there, even homeboy Tony Parker.''

Drake is believed to have started the fight when his entourage sent a note to Chris about his ex-girlfriend Rihanna.
