Travis Kelce fueled engagement and baby rumors with girlfriend Taylor Swift while discussing lab-grown diamonds on his podcast with his brother, Jason Kelce.

“You can’t tell me that dude wasn’t made in a f–king lab over there in France,” he said on the “New Heights” podcast Wednesday, referring to NBA star Victor Wembanyama, who is over 7 feet tall.

“Lab-grown diamonds, that’s a lab-grown f–king NBA player. Can’t wait til I f–kin’ make one,” the Kansas City Chiefs star, 34, added. Jason quickly interjected, pleading with his younger brother to stop the conversation before he caused conspiracy theories to emerge.

“Don’t do this. Do not give any of these other conspiracy theorists anything else to latch onto, please,” the retired NFL star, 36, said.

Fans on social media reacted to Travis’ new comments. “This will get people to tune in that’s all I think this is if they we’re engaged or getting engaged I think Jason would be the one to hint at it not Travis also I really think it would be a family ring or vintage ring not a new ring,” tweeted one person.

“Mini me in coming [sic] ,” added another. “Before he was begging for a date and now he was begging for a baby,” said a third person.

“DONT TELL ME THAT U CANT WAIT TO MAKE BABIES WITH MY TAYYY TRAAAAVVVVVV WHATS GOING OOOONNNN,” wrote a fourth user.

Other fans warned the Swities not to look into the tight end’s remarks too much because the brothers often joke on their show. “you guys need to understand that they joke a lot in this podcast pls don’t take it seriously,” tweeted one person X.

“These theories [are] what brings hate to him and their relationship… Just stop and learn to take a joke,” added another.

Whenever Travis does decide to get down on one knee and propose to Swift, also 34, he already has an expensive option as an engagement ring.

Page Six exclusively reported in January that Philadelphia-based jewelry designer Steven Singer offered the three-time Super Bowl champ a $1 million custom-made ring for the proposal. “I recognize that the most renowned couple globally has an abundance of options when it comes to choosing engagement rings, should they decide to tie the knot,” the owner of Steven Singer Jewelers told us.

“If they do, I would be honored to help design a truly extraordinary ring exclusively for them.” Page Six also reported that Travis is planning to propose to Swift this summer.

“Taylor and Travis discussed it and there is a plan,” an insider told us in January. “They will get engaged on their one-year anniversary in July.”
