The Roar hit maker was spotted rocking up to the GQ and Youtube After Party in one of the most plunging tops we have ever seen.

In fact as she made her way into the swanky venue it looked like the superstar’s assets were about to pop out at any moment.

The star faced an extreme backlash after making not one but two digs at pop legend Britney Spears while on the Grammys’ red carpet.

When asked by Ryan Seacrest why she has taken a long time with her upcoming album, the kooky star replied: “That’s called taking care of your mental health”.

When pushed as to how that is going she laughed: “Fantastic. And I haven’t shaved my head yet”.

Britney famously suffered one of the most public meltdowns of all time after shaving her head in February 2017 – almost a decade ago to the day.

Grabbing a razor the troubled star removed all of her locks in front of the paparazzi before going to get a late night tattoo.

Later down the carpet Katy made another dig at the Gimme More star while chatting about her new hair.

“It’s like the last colour in the spectrum that I can do,” she said.

“I’ve done all of them and the only thing left to do is shave my head, which I’m really saving for a public breakdown.

“I’m down for that. I’m almost moments away from that, obviously.”
