Katy Perry won't be lighting fireworks to welcome a new baby as the rumors that she's pregnant, with John Mayer as the father, are reportedly simply not true.

The rumor that Katy Perry is pregnant was first reported by OK! magazine, which said that the "Fireworks" singer is two-months on the way and was picked up by several news outlets.

That's also one of the reasons why Katy Perry and John Mayer are rushing an April wedding, the report alleged.

"The buzz in her close group of friends is that she's two months pregnant," an insider allegedly told the magazine.

The insider claimed that John Mayer and Katy Perry are serious about the relationship and are committed to take it to the next level with an April wedding.

"It's different this time around. Both of them have changed, and after nearly a year apart they've realized what they want," the insider added.

 "She'd be nervous about telling him," a supposed friend of the actress told the tabloid. "Because he hasn't been the most reliable guy in the past. But he's sworn to her that he's a changed man - and when he told her about his hopes for having a baby together, Katy fell in love with him all over again."

However, Gossip Cop said there's no truth to the OK! report that Katy Perry is pregnant.

"A source close to Perry exclusively confirms to Gossip Cop that the singer is NOT pregnant," the website said. "Our insider stresses that Perry is focused on her Prismatic World Tour, which has Perry in Europe throughout February and March. She'll then travel to Asia for shows in April and May."

The fact that Katy Perry didn't cancel her Prismatic World Tour is proof enough that she's not pregnant, Gossip Cop added.

"Of course, OK! also claimed Perry and Mayer were 'having a baby' in 2013, and that Perry could 'slip up and get pregnant' with Pattinson's baby last year," it said. "Basically, its sources have not gotten any better over time."
