Whitney Houston has dumped Brandy's younger brother Ray J after a raunchy sex tape featuring him and ex-girlfriend Kim Kardashian was leaked on the internet.

The 43-year-old has been dating Ray J, 26, for several months and the two were reportedly living together.

According to veteran Hollywood columnist Janet Charlton, Houston became outraged when the tape was leaked online and ended the relationship.

Ray J, real name Ray Norwood, had been helping Houston work on her comeback album and was also offering her support in adapting to her new sober lifestyle.

Houston was spotted dining with estranged husband Bobby Brown on Sunday, but insists reconciliation between the pair is not likely.
