Splitsville? Na na na na! Selena Gomez is shutting down rumors that her BFF Taylor Swift has called it quits with Calvin Harris. In fact, the "Good for You" singer was taken aback when talk of a possible breakup came up during an interview on SiriusXM's Andy Cohen Live on Monday, Oct. 12.

"What?! Oh, I don't know. I think I would have found that out," Gomez, 23, told radio host Cohen. "I didn't even know — is that a rumor? Oh gosh, of course. This is honestly so stupid." 

She added of the Scottish DJ: "He's very tall. [He's] for sure [very handsome]." (Us Weekly broke the news in April that Swift and Harris were dating.)

Gomez has always supported Swift with her love life — and music. The "Shake It Off" singer recently returned the favor when Gomez's second studio album, Revival, dropped on Oct. 9, and Swift texted Gomez about the release.

"She was listening to the album and she's been super supportive — obviously with everything I've done because she's been my best friend for eight years," Gomez explained to the Watch What Happens Live host.

"But this [album] specifically was really important to get her respect in that matter," she continued. "So she just sent me this long message and I was just, like, 'Thank you! I love you!' She's very sweet."
