Katy Perry gave onlookers a glimpse of her underwear at Radio 1's Big Weekend
The 32-year-old – who paid tribute to the victims of the Manchester terror attack during her jam-packed set list – flashed her white knickers as she showed off her dance moves in a sparkling ensemble.
Katy donned a slinky silver mini dress for the music extravaganza, which she teamed with a matching jacket.
The beauty highlighted her toned pins in a pair of fishnet tights and she completed the sizzling get-up with a dangling statement earring and some metallic eye make-up that matched the rest of her outfit.
Katy’s latest appearance comes after she broke down in tears at an intimate London gig on Thursday night following Monday night’s bombing that happened moments after Ariana Grande’s Manchester Arena show.

The US popstar appeared at a small gig for her fans at The Water Rats pub – where she made her UK debut a decade ago – and urged the crowd to “not let terrorists win”.
The Firework singer, who was at launch party for the new Capital Breakfast show with Roman Kemp, also dedicated a song to the 22 people who were killed when a suicide bomber detonated a device not long after Ariana's last song.
An emotional Katy told her adoring fans: “This week has been really hard. It sucked. It was hard for you guys and it was hard for me because we all love music."

Katy went on: “We all listen to the same music. And you think about it and you think that’s my friend, that’s my sister, that’s my brother, that’s my cousin, that’s the person that loves music. It’s awful.
“And whatever you can do to help, you should. And if you can’t do anything that’s fine. But what you should do is not let them win.”
Before belting out her 2012 hit Part of Me, she said: “I’m going to sing this next song for them. They can never take that part away from us ever. Ever. Ever.”
