Mary-Kate Olsen Mary-Kate Olsen Put the champagne back in the fridge and the booties back in the bottom drawer...

It turns out Mary-Kate Olsen is not in the family way.

And we know this because we've heard it straight from the horse's mouth, well, at least the jockey's mouth.

"Mary-Kate is absolutely not pregnant,"  her rep staunchly told People magazine yesterday.

So how did all this hoopla begin in the first place?

Well, the National Enquirer broke the untrue news after citing a source who suggested that 22-year-old MK was expecting, purely because her weight had supposedly shot up to 102 pounds.

"Mary-Kate has been looking a lot rounder recently," the source told the National Enquirer.

"It's good, she's put on weight since she has previously suffered from anorexia, but a lot of people think that she might actually be trying to conceal her pregnancy."

Seriously?

The mag immediately speculated that the baby was conceived with New York artist Nick Lowman, the stud whom the tweeny star is dating at the mo.

As you were folks.
