There has been speculation that Rihanna and Chris Brown are once again romantically involved.

Hollywood Life reports that the R&B singer has recently tweeted a song lyric from a Beres Hammond song, "They Gonna Talk." It seems that lyric is in reference to her reuniting with Brown, who had physically assaulted her in 2009.

When they see me with you, wonder what the crowd would say? When they find us together, what will all the people say?," the tweet read.

This can be in reference to Rihanna possibly coming out publicly about a relationship with Brown, as she knows there will be a media frenzy as well as criticism.

Rumors have been circulating for quite some time that this romantic reunion may happen and many have spoken out, warning Rihanna not to get involved with Brown.

Bishop Vibert Lowe, a family friend of Rihanna and her pastor from Barbados, says that Rihanna should stay away from Brown. He also does not condone her current lifestyle.

"A lot of people have been praying for her and hoping that she will drop these bad habits. We feel it's wrong for her to behave like this. As a young lady she's not setting a good example," Lowe told The Sun about Rihanna being linked to Brown as well as the way she displays herself publicly.

"After all he did, I'd tell her to steer clear of him," he added.

Actress Reese Witherspoon has previously spoken out about Rihanna's possible relationship with Brown.

According to Hollywood Life, Witherspoon speaks with her kids about abuse in order to help them understand the situation. She feels that it is important that they know what is "absolutely not acceptable."

Rihanna was seen leaving Brown's dressing room at the Grammy's this year. Friends of hers have commented that the singer is engaged to Brown, as they have been dating secretly for the past year, but there has been nothing to prove that this is true.

Brown, however, is currently said to be dating Vietnamese model Karrueche Tran. Rihanna has reportedly been making negative tweets towards the model.
