Rita Ora is no doubt totally over that time her ex boyfriend Calvin Harris caused severe delays to her second album, but that doesn't mean she isn't allowed to make the odd snide comment about it…!

The singer took to the stage at BBC Radio 1's Big Weekend yesterday (May 24), where she included in her pop-tastic set 'I Will Never Let You Down', the number one hit her and Calvin co-wrote.

"You know when there is a song and no matter what happens the music still stands for itself," she told the crowd before launching into the number, reminding everyone of that time he put a stop to her performing it altogether.

Seeing as Calvin's new girlfriend Taylor Swift was also performing on the same stage later that day, it must've been a tiny bit awks what with the chances of them bumping into each other being pretty high!

Rita also performed her brand new track 'Poison' for the first time, which is the second official single from her forthcoming new album.
