The Turn Up The Music singer sat next to girlfriend Rihanna at the music bash, and the couple could be seen cuddling together in the audience at the ceremony.
But Chris - who was arrested for beating up Rihanna at a pre-Grammy awards party four years ago - appeared to ignite Adele's wrath when he refused to join the rest of the audience in a standing ovation for Ocean when he won Best Urban Contemporary Album, The Sun said.
Chris, who had also been nominated in the same category, and Frank are thought to have had an altercation over a parking space two weeks ago.
The Sun said that Rolling In The Deep singer Adele glared at Chris when he remained seated, and was later seen giving him a piece of her mind.
Meanwhile, Rihanna has sparked more speculation over her relationship with Chris, after she appeared to be wearing an engagement ring at the event.
