They will perform in New York Wednesday, August 29, during a tribute to Michael Jackson's Bad album which will celebrate its 25^th anniversary on August 31.

The concert which will be broadcast from Pepsi's Twitter page livestream will allow viewers to influence elements of the show. When Nicki Minaj performed her Summer Beats date on August 14, fans helped shape her set list.

During the Bad celebration, Ne-Yo will sing Jackson's "I Just Can't Stop Loving You" as well as songs from his forthcoming album, R.E.D.

Rihanna shed her tough girl exterior when discussing ex-boyfriend Chris Brown during an interview with Oprah Winfrey on her television show "Oprah's Next Chapter." The pop star's eyes were welled with tears as she described having conflicting feelings about Brown after he assaulted her in 2009.

"I lost my best friend," Rihanna explained during the emotional conservation filmed in her home country of Barbados. "Like everything I knew was switched. Switched in a night. And I couldn't control that. So I had to deal with that, and that's not easy for me to understand or interpret. And it's not easy to interpret on camera, not with the world watching."
