RIHANNA, CHRIS BROWN: SINGER TWEETS ABOUT ‘FORGIVENESS’

Rihanna spent Sunday on the set of her new music video, "Diamonds," for which she donned a sexy see-through gown.  But we have a feeling RiRi had something else on her mind during the shoot--namely her controversial ex, Chris Brown, with whom she was spotted Saturday night. Rihanna and Brown were caught on camera canoodling at a launch party for his Qubeey website at Playhouse nightclub in Beverly Hills.
