Kanye West has confirmed he has split from Amber Rose. The "Stronger" rapper and shaven-headed model began dating earlier this year, but have decided to end their romance.

Kanye West and current radio darling Lady GaGa are heading out on a North American tour together. The "Heartless" rapper and "LoveGame" singer will begin touring in the fall.

Word is that GaGa won't be an opener, nor is it a co-headlining show, but instead the two acts will perform together throughout the show in one long set.

Rihanna is not dating anyone. The "Umbrella" singer has been linked with a series of handsome famous men, including rapper Kanye West and Aubrey Graham, since splitting from Chris Brown - who is accused of assaulting her in February - but is happy to concentrate on her career for the moment.

A source said: "Rihanna needs the focus to be on her talents right now, not the bumps in her personal life. She doesn't want anything else to overshadow her career."

Rapper superstar Kanye West denies smashing a photographer's camera last year. The "Stronger" hitmaker has pleaded not guilty to assault, theft and vandalism charges on Friday.

West, 31, and his road manager Don Crawley, 33, was charged with two counts each of misdemeanor vandalism, battery, and grand theft stemming from a fracas with the paparazzi the Los Angeles International Airport on September 11, 2008.
