The Big Bang Theory's Kaley Cuoco has made "unraveling the mystery" quite easy for speculative fans who thought the 27-year-old star might be with child. On Nov. 9, she took to Twitter to clear up the rumors. 

"I would like to make something very clear to anyone who cares," she wrote on her verified account. "I AM NOT EFFING PREGNANT. Do with that what you will." 

It all started when an online blind item claimed the star was expecting, and that she and fiancé Ryan Sweeting rushed into their engagement after only three months of dating before the supposed baby's arrival. 

But Cuoco makes it pretty obvious that she's not buying a crib, at least, not yet. Fans have been curious about the actress's whirlwind romance. On the Nov. 7 episode of The Ellen DeGeneres Show, Cuoco revealed that she knew Sweeting was the one after knowing him for only two days. 

"I know it looks a little crazy to some people," she admitted to DeGeneres.

As of the Oct. 5 Veuve Clicquot Polo Classic, the newly engaged couple hadn't made any wedding plans. 

"We are too busy to wedding plan," Cuoco told reporters. "In a year we will start talking about it. We are enjoying being engaged."
