Robert Kraft Says T. Swift Should've Dated 'Better Looking' Gronk Over Kelce

Ear muffs, Camille Kostek 🙉 ... Robert Kraft believes Taylor Swift chose the wrong superstar tight end, JOKING the international pop star should've picked Rob Gronkowski over Travis Kelce!!

Why?! Well, Gronk's hotter! 🔥

The New England Patriots owner joined Fanatics Collectibles to celebrate National Trading Card Day with collectors at World Champion Sports Cards in West Palm Beach, FL ... when the billionaire was asked about his relationship with Swift, which goes back more than a decade.

“Her first stadium concert was on my birthday in 2010, June 5. We convinced her and her family that she could sell out a stadium," Kraft said of his decade-plus old convo with T.S. and her fam.

Kraft continued ... "So when she came to view the Chiefs play the Patriots this year at Gillette, I gave her a framed ticket from that concert, June 5, 2010. Think about it, she was like 18-19 and she’s done pretty well since then."

And, that's when Robert made a funny.

"Except maybe she should have been dating Gronk -- he’s better looking!”

Of course, Taylor and Travis are happier than a pig in you know what ... and Rob and Camille have dated for nearly a decade.

In other words ... everyone's happy!

When he wasn't breaking up couples (WE KID!), Kraft was hanging out with scores of fans who came out to celebrate Topps Hobby Rip Night (the trading card company celebrated at 400 shops across the country). One young fan even left with a signed Tom Brady jersey.

Kraft was just one of many huge stars who showed up to hang out with fans and collectors ... including Kevin Durant, Odell Beckham Jr., Joe Burrow, Ronald Acuna Jr., Steve Aoki, Meek Mill, Johnny Manziel, and TB12.
