While X17 reported on Wednesday that Katy was spotted leaving a Century City doctor's office, where she reportedly had her first sonogram, a rep for the "Hot N Cold" singer told Us Weekly that Katy is not pregnant.
And Katy too weighed on the matter on Twitter on Wednesday night, telling one fellow social networker that she is currently menstruating.
"ur gonna make me cry, maybe that's my period tho. THAT'S RIGHT I'M BLEEDING. Face," she wrote. "Better luck next month peepz."
As previously reported onAccessHollywood.com, Katy's rep confirmed earlier this month that she and Russell are engaged.
Russell proposed to the singer while the two raven-haired stars were vacationing in India in late December.
