Twitter hints at Rihanna, Brown reunion LOS ANGELES, Dec. 31 (UPI) -- A series of mushy tweets has U.S. celebrity watchers wondering if Rihanna is looking to ring in the New Year with former flame Chris Brown. The musical pair exchanged tweets recently including the "love" word, even though Brown is under a restraining order and was arrested for roughing Rihanna up in a highly public domestic incident in 2009. The Los Angeles Times said Saturday the former couple follow one another on Twitter. Brown sent a "Love U" tweet out Thursday that Rihanna responded to promptly in the same vein. Brown's mom earlier this month sent out her own tweet that appeared to be an overture to Rihanna. It appeared the singer took it that way because she fired back "Miss+Love U 2," the Times said.
