There was apparently A LOT of ex dodging at the 'Billboard Music Awards' on Sunday (May 17), with Harry Styles and Rita Ora trying their best to avoid Talvin’s PDA.

Talvin - AKA Calvin Harris and Taylor Swift - were busy flaunting their romance at the ceremony in Las Vegas, which we’re sure was pretty awks for Hazza (who dated Tay) and Rita, who used to be Calvin’s lady love.

Still with us? According to The Sun, Styles was the only member of One Direction NOT to attend T-Swizzle’s after party, instead hopping on a flight from Sin City to LA.

A source told the tabloid: “(Harry) realised the party wasn't a good idea, so flew back to LA solo."

His spokesperson also confirmed that he missed Swift’s bash, adding: "Harry didn't stay in Vegas after the awards, so didn't attend any after-show party."

Meanwhile, Ora also dodged the Talvin bullet by opting to stay backstage throughout the event, with an insider claiming: “Rita was backstage the whole night to avoid Calvin and Taylor.

“The romance is big news - she wanted to avoid an awkward encounter or being pictured reacting.”

They added: “Taylor was introducing all her mates to Calvin by his real name Adam, telling everyone how happy they were. There's no love lost between them."

'Bad Blood' anyone?
