Taylor Swift's mom has seen a notable difference in her daughter amid the singer's romance with Travis Kelce.

The "Fate of Ophelia" singer's mother Andrea Swift, 67, made a rare comment about her future son-in-law in a snippet of a sit-down interview shared to Thursday (November 13) in the new trailer for Swift's upcoming Eras Tour docuseries The End of an Era.

"Travis Kelce, he brings a lot of happiness," she said.

The trailer also featured sweet moments between the couple, from Swift and Kelce practicing for his Eras Tour debut and sharing a kiss backstage to the musician wearing a Kansas City Chiefs shirt in rehearsals and watching her beau play in a game on TV. The pair also bonded over "basically [having] the same job" in a phone call while Swift was traveling in a car.

"You've got teammates, I've got teammates," Kelce can be heard saying, as Swift chimes in, laughing, "You've got Coach [Andy] Reid, I've got my mom."

The happiness that Andrea spoke of has resulted in a soon-to-be marriage. Swift and Kelce announced their engagement August 26 after two years of dating, sharing photos of her stunning diamond ring and the romantic garden proposal that she later admitted he "crushed" despite being "nervous."

Swifties will potentially see more sweet interactions between the newly-engaged couple in The End of an Era, a six-part docuseries capturing behind-the-scenes moments of the "seismic, momentous period of time" in Swift's life that was the Eras Tour.

The End of an Era premieres December 12 on Disney+.
