sunglasses Kaley Cuoco sweats coffee Ryan Sweeting

Kaley Cuoco may be over the moon about her engagement to hunky tennis star Ryan Sweeting (and they uh, sorta got married on the Ellen DeGeneres Show), but a baby is definitely NOT on the way for the lovebirds!

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

X17 photographers snapped the couple grabbing coffee on Sunday, and this was just a few days after they had a mock wedding with DeGeneres. As you may know, Cuoco and Sweeting got engaged after dating for about ten weeks, and on the show she admitted, "I know it looks a little crazy to some people."

But what was even crazier was their little trip down the aisle! DeGeneres jokingly gave Cuoco a veil and a tennis ball necklace, and Sweeting came onstage as "Here Comes The Bride" played. Cuoco couldn't stop laughing but before one of Ellen's producers declared the duo man and wife, the pro athlete asked, "This isn't legal, right?" As far as we know, he wasn't joking ... but watch the video below and see for yourself:
