Rihanna and Chris Brown were found by chance in Ny nightclub

The former partner, who broke in 2009 after a domestic violence altercation by Chris sat at different tables in the nightclub SL New York on Saturday, although witnesses say they were both aware of each other's presence at the club .  "Chris came to SL with a group of friends and Rihanna tried to get away from him with his own. They sat far enough away from another to avoid having to talk, but close enough to each other monitored. Chris sent Rihanna two bottles of champagne brand Ace of Spades ", a source told the New York Post.  The artist had previously agreed with Chris and her boyfriend, Karreueche Tran, Los Angeles in a far less friendly encounter.  "Chris and Rihanna were seated a few tables away from the other and glancing were threatening all night. Nobody was talking. Rihanna was escorted to the bathroom several times and tried to go near the desk of Chris, but without even blink, "said another source.  Rihanna, who in recent months has recorded two singles with rapper - "Turn Up the Music" and "Birthday Cake" - previously confessed that he had hit a lot of negative reaction to people working with her ​​ex-boyfriend.  "I knew people would be surprised by our decision to work together but do not understand that people think is wrong. In my head is just music. I mean, if I were with him as his girlfriend, that would be different," said .
