Rumors are circulating that Taylor Swift is allegedly aiming to get pregnant with Calvin Harris' child as soon as possible.

According to reports, Taylor Swift and Calvin Harris have purportedly been checking out baby names and nursery designs recently, sparking speculations that they're pregnant, or at least trying to be.

"Since pal Jamie King named Taylor godmother to her newborn son Leo, Taylor's biological clock is ticking like Big Ben," Celeb Dirty Laundry reported. "Swift claims she wants two kids with Harris by the time she's 30. Swift is 25 now, so she's got to get busy to fill that 'blank space.'"

So it seems that Taylor Swift doesn't want to get pregnant right away, and has more or less 5 years lead time ahead before she starts aiming for that baby bump.

Even so, is Calvin Harris freaking out with Taylor Swift's eagerness to become pregnant with his baby?

"What's kind of crazy is that her baby fever has not scared off Calvin Harris," the website added.

"The 31-year-old DJ/musician is totally down to impregnate his girlfriend of six months and has even been out house shopping with her in LA and they've been talking baby names, planning nurseries, discussing when they want to start trying to get pregnant and all the nitty gritty details of putting their lives together and adding a baby to make three."

Pregnant or not, Taylor Swift and Calvin Harris seem to be nurturing a serious long-term relationship. According to celeb body language expert Tonya Reiman, Taylor and Calvin's movements seem to show that they are smitten with each other.

"As Taylor Swift and Calvin Harris walk, you can tell the two are in-sync," Reiman told Dish Nation. "Calvin is leading the way for his lady. They are mimicking each other's body language - fingers interlaced (signal of romance) - versus regular handholding and the opposite arms both down."
