Katy Perry has denied rumours that she is pregnant with her first child.

The 27-year-old singer shot down the reports that she is expecting and was adamant in her response.

There was a baby bump buzz surrounding the Firework singer at Sunday's American Music Awards (AMAs) when she seemed to have a thicker midsection than normal.

"Hell, no!" she told Hollyscoop who asked her if there were children in the near future for her and husband Russell Brand.

In fact, she said it was more about the food she was eating than a baby on the way that explained her fuller figure.

"I like In-N-Out Burger and Taco Bell and if you want to make that pregnant that's your problem," she told The Insider. "I still love drinking alcohol so not yet."

At her concert in Madison Square Garden last week, Katy also joked to crowd about her "bloated belly."

She said that if they saw her rubbing her stomach, it was because she had been having fun eating the "delicious" food in New York City.

But Katy has said in the past she does want to become a mother but it's not currently the right time.

"Children is one of the reasons you get married," she told Ellen DeGeneres last month. "Especially to the person that you marry. You think, that person is going to be a good partner, a good parent. But I'm not sure it's time yet. We'll see, ya know?"

"If it doesn't hurt the first time, I'll keep popping them out!"
