The same day, Swift's BFF Selena Gomez came to her pal's defense on Andy Cohen's SiriusXM radio show -- and she hadn't even heard the rumors!
"I think I would have found that out -- is that a rumor?" she asked. "This is honestly, it's so stupid. I'm pregnant every week, she's gonna be pregnant. It's so stupid. You can't really read that stuff."
Swift and Harris took their romance public in May of this year, when they cozied up in front of the cameras at the Billboard Music Awards. In June, Swift made it Instagram official (the only true official there is!) with this adorable snap of the pair goofing off on a swan floatie.
