Rihanna and Chris Brown appear to be over their issues with Drake.

The couple - who recently reunited despite Chris still being on probation for beating her in 2009 - were spotted singing and dancing together to her ex-boyfriend's hit song 'The Motto' in between kisses at her star-studded Halloween bash last night (31.10.12).

A source told HollywoodLife.com: ''Ironically, Drake's 'The Motto' song came on, even though Rihanna requested Drake not be played. I guess she and Chris didn't want to make a scene so instead, they danced to it. And they rapped the song word for word. I don't think Drake was an issue at all between them.''

Earlier this year, the 'Rude Boy' singer - who collaborated with Drake on their hit 'Take Care' - was allegedly caught calling him an ''a**hole'' at the MTV Video Music Awards, shortly after he was accused of being involved in a New York bar fight with Chris.

The 24-year-old 'Diamonds' singer - who had a cosy dinner with 23-year-old Chris' mother Joyce Hawkins in Hollywood last week - is said to have been all over Chris at the party in GreyStone Manor where she was dressed as a bride and he wore a terrorist costume.

An insider said: ''Rihanna was showing such desperate signs [for Chris]. She had her hand around him and he was eating it up. Every time she stood up, she would rub his head as if he were a little puppy.''
