The lovebirds arrived at the venue separately, and Rihanna didn’t know that Chris was also expected at the event, an insider told Daily Mail.

"Rihanna refused to sit with or even near Chris – and when Chris noticed she was there, he made a huge show of rubbing his presence in her face," the source revealed.
