Last week Rihanna put rumours of a bitter feud with Beyonce behind her as she blew a kiss to the pregnant star at the Grammys.

An eagle-eyed fan spotted the exchange when the two women thought no one was looking.

They were seen dancing in the audience, when Rihanna turned to look over her shoulder at Beyonce.

RiRi then blew some air kisses at Beyonce, with the Drunk In Love singer responding with a kiss and a huge smile.

She also sent fans crazy after they spotted her downing shots during the prestigious awards.

The Bad Girl singer sat with a pal and fellow music maker Ed Sheeran as the ceremony rolled on, but made sure she had a little something to keep her going.
