Katy Perry "Jealous" Of Beyonce Baby

It looks like Russell Brand's 'California Gurl' is getting broody.

Reports last week said that Katy Perry wants babies asap, and has even asked Russell to take a career break so the pair can focus on making a baby.

And after Beyonce announced she and Jay-Z are expecting their first child at the MTV VMAs, Katy has revealed she's envious of their baby news.

"That warmed the cockles of my heart," Katy told Capital's showbiz reporter Kevin Hughes.

"I'm jealous!"

And later Katy offered her child-minding services by tweeting, "Also...@Beyonce me & @rustyrockets are avail to baby sit anytime! We'z real responsible...ish :P #HIPHOPBABY".

After picking up three awards including the prestigious Best Video gong for her single 'Firework', Katy Perry says there's plenty more to come.

"I'm still on my tour and that's been a year long thing, so it's been really gruelling and I'm just trying to take that one day at a time and get through that," Katy revealed.

"And make sure I give the best damn performance every single time, every single night.

"But I don't wanna feel like I've peaked just yet. I've got way too many outfits to go through."
