In another promo clip with a lighter mood, Oprah and Rihanna are shown having fun together while driving around and talking about her native home of Barbados.

The TV host said that she expected Rihanna to be "an edgy 'badass'" but after speaking with her in-depth, she was surprised to learn that the artist "defied all her expectations," according to The Huffington Post.

Recent circulation has stirred when eyewitnesses saw Rihanna and Brown spending time together while they were both vacationing in Europe. Reports claimed that the two spent alone time together going to restaurants and that Brown was even seen going to Rihanna's private yacht alone in the evening.
