Taylor Swift confirmed she's not eyeing a castle with Calvin Harris. However, rumors are abuzz that it's a baby she wants.

In a report on Hollywood Life, it was mentioned that baby fever has gotten to the "Bad Blood" singer after becoming godmother to Jaime King's second child, Leo Thames.

"She's got baby fever and wants at least two kids by the time she's 30," an insider told the Life & Style as quoted by the source above. "Calvin and Taylor talk about it all the time and are always joking about weird Hollywood baby names and how their kids will be freakishly tall like them. They can't wait!"

The report even said the pair is ready to build a nursery if the need arises.

"Taylor is super excited to start a family with Calvin and even has their nurseries all planned out," the source added. "Calvin is excited, too. He sees how great she is around babies like her godson."

None from their camps have yet to address the Taylor Swift Calvin Harris baby plan rumors. But the two were spotted together on Tuesday in California after a date.

Last year, Swift had no inkling at all about building her own family.

"I don't know if I'll have kids," she said in the InStyle November 2014 issue. "It's impossible not to picture certain scenarios and how you would try to convince them that they have a normal life when, inevitably, there will be strange men pointing giant cameras at them from the time they are babies."

She echoed the same concern a year later.

Two months before the Taylor Swift Calvin Harris baby dream rumors surfaced, E! Online reported that in an interview with ITV News, Swift opened up and said that in a decade, she hopes to already have her own family but expressed that she already worries about protecting them from all the media frenzy.
