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.
