Are Taylor Swift and the Jonas Brothers cooking up a collab? Nick Jonas coyly addressed the speculation in a video posted to TikTok. The clip showed him playing with the green screen flip effect until it landed on a screenshot from DeuxMoi, an Instagram account that shares rumours about celebrities. "Collab," it read. "Jonas Brothers x Taylor Swift." "This effect is cool," Nick wrote underneath the video. Earlier that day, Taylor moved up the release date of her re-recorded Red album from Nov. 19 to Nov. 12. As eagle-eyed fans pointed out, Nov. 12 just so happens to be National Pizza With Everything Day. Coincidence? Maybe. But Taylor also commented on another one of Nick's recent TikToks with a pizza emoji and the word "iconic." The video showed him eating a slice of pizza with her hit ME! playing in the background. Nick wasn't the only one to spark speculation. Joe also posted a picture of himself standing in front of a pizzeria on Instagram and wrote "Looking for [pizza emoji]." While the answer to these rumours may be a blank space for now, they've still left fans buzzing.
