Pop star Katy Perry is planning to auction off her bubblegum-pop stage costumes.
Perry, 28, who has undergone a vamped-up makeover, said her new costumes would be more matured ones, reported Daily Mirror.
"I have a warehouse here in LA and I'll probably do an Elton John-type auction. But I am still going to be bringing the bling. You'll see a bit more of a grown-up version of me, which does not equal boring," she said.
The singer is also pouring all her break-up emotions with husband Russell Brand into her new song 'Raw'.
"This new song is called 'Raw'. It's a bit of a self-empowering type of song. I wrote it because I was sick of keeping all these feelings inside and not speaking up for myself, which caused a lot of resentment. Obviously I've been through a lot of therapy since my last record and that's what this is about," she said.
