Despite the rumors circulating online, Katy Perry is not pregnant.

The star's rep tells that reports claiming Perry -- who got engaged to Russell Brand on New Year's Eve in India -- was getting a sonogram and showing off a baby bump were "not true."

Plus, the singer, 25, took to her Twitter account to say that she was on "my period" Wednesday evening.

"Better luck next month peepz," she posted.

Still, Perry didn't do much to squash pregnancy rumors this past Sunday, when she and her fiance scoped out booties at a baby boutique in North London.
