FKA twigs 'not happy with Katy Perry'

FKA twigs was apparently not impressed with Katy Perry's recent behaviour around fiancé Robert Pattinson.

Robert and Katy have been friends for a long time, and were even rumoured to have dated at one point. Despite the alleged romance they've stayed close, which reportedly hasn't bothered FKA - until now.

At last week's (beg16Nov15) GO Campaign Gala Robert posed for a photo, sitting in between the two singers. And while things looked friendly, sources reveal tensions were high.

"twigs is used to being shoved out of the way by Rob's Twilight fans but she never expected to get that 'third wheel' feeling with Katy," an insider told Britain's Grazia magazine.

"twigs is not the jealous type and Rob has always denied any serious feelings for Katy, but seeing how touchy-feely they were and how Katy was all over Rob would no doubt make twigs feel uncomfortable. Katy kept referring to their past, the good old days. twigs would of course feel excluded."

Katy and Robert's rumoured fling happened in 2014, after the pair were supposedly spotted kissing at a Hollywood party following the premiere of Robert's move The Rover. It came at a time when Katy had split from her on-off boyfriend John Mayer, and Robert and Kristen Stewart had called it quits.

However FKA, real name Tahliah Barnett, doesn't have anything to worry about. In September (15), during her set at British festival Bestival, onlookers noted how loved up Robert looked.

"He kept his head down and looked like he was really enjoying watching her perform," a source told Britain's Metro newspaper. "He looked very proud of her and completely in love. At one point he sang along to one of her songs - he looked like her No.1 fan."
