Showbiz Spy reports: Meanwhile, the svelte star has confessed she’s too lazy to work out.
“I almost always wear Spanx,” she said. “I like to say I run on the elliptical for 30 minutes watching CNN, but I don’t do it often enough. So I’m just like, ‘Oh, I guess I’m not fitting into this Lanvin dress for these couple of months.’”
It’s been claimed that Katy is planning to live with boyfriend John Mayer.
“John and Katy have decided to give it a proper go and want to find a place in LA to share,” a source said.
“But lots of people are willing them to fail. They row a bit and have quite a turbulent up-and-down relationship, despite it only being a few months old. “Many of her friends are certain it will all end in tears.
“But that’s brought them closer in a way. It’s given them an ‘us against the world’ mentality. “They are together virtually every day. “They hang out at John’s place, cooking, watching movies and playing music. “They take the odd trip away but generally they’re trying to keep it behind closed doors.
“Introducing John to her parents was a huge step for Katy and it proves she’s 100 per cent committed.”
