Katy Perry's 'The Project' Performance & Interview: Watch

Katy Perry stopped by Australian TV show The Project on Tuesday (March 10) to debut her new single “Never Worn White” live for the first time.

Clad in a gold-embellished coral gown and showing off her growing baby bump, the pop star performed the romantic ballad backed by a pianist and string quartet. “No I’ve never worn white, no/ But I really wanna try with you/ Oh I’ve never worn white/ But I wanna get it right/ ‘Cause I really wanna say ‘I do,'” she belted.

Ahead of taking the stage, Perry also sat down with the show’s panel of hosts to chat about her surprise pregnancy announcement at the end of the music video for the track and how she hid the news for so long. “I’m definitely in it; there’s no hiding it and no passing it off as, like, you know, just a breakfast burrito,” she said. “I’ve always been a very curvy girl and I love to eat, so there had been rumors in the past that people had thought that I was pregnant…and now, they’re right! They’re more than right, yes. These are not cookies in my belly.”

The American Idol judge also opened up about meaning behind her new single and how it was inspired by her relationship with fiancé Orlando Bloom. “I thought that this song would be a really good first start for this next time in my life,” she said, “to set the tone and to really talk about the vulnerability of commitment, and sometimes how amazing it is, but also how terrifying it can be. And a lot of stuff does bubble up when you’re about do that big number.”
