Kaley Cuoco is 'not effing pregnant'

(UPI) -- There's a host of tabloid reporters out there on permanent baby-watch for celebrities like Kaley Cuoco, whose quickie relationship with Henry Cavill and subsequent engagement to tennis player Ryan Sweeting has put gossip hounds on high alert for more news.

But that doesn't mean the 27-year-old actress is starting a family anytime soon.

"I would like to make something very clear to anyone who cares. IAM NOT EFFING PREGNANT," the Big Bang Theory star tweeted Saturday. "Do with that what you will."

Sweeting proposed to Cuoco in September after three months of dating.

"By day two I was like, ‘Oh my god.' It was so unbelievable. I said, 'This is it, this is it,'" she has said of their relationship, telling Ellen DeGeneres last week that she knows her quickie engagement might seem "a little crazy to some people."
