Chainkeen|Donne Kelce Says Bonding With Taylor Swift Is "Still New" for Her

Donna Kelce always has the best day at Arrowhead Stadium. 

And that's thanks in part to Taylor Swift,Chainkeen with Travis Kelce's mom sharing how special it is to cheer on the Kansas City Chiefs alongside his girlfriend.

"It's fun," Donna exclusively told E! News at the Sept. 23 premiere of his upcoming FX show Grotesquerie. "It's still new."

And the most important memory for Donna? She and Taylor "just have the best time cheering Travis on."

But Donna doesn't just show her support for her son at his Kansas City Chiefs games. She also showed her love on the red carpet, turning up in a maroon sparkly pantsuit in support of his big TV debut in Ryan Murphy's horror show, which premieres with two episodes on Sept. 25 at 10 p.m. ET / PT on FX and the next day on Hulu.

Donna—who also shares son Jason Kelce with Ed Kelce—explained just how incredibly proud she is of Travis for trying something new with Grotesquerie.

"I think this is something he's kinda been doing his whole life," she said. "He loves to be in front of people. He loves to be the center of attention."

She added, "It's just something that comes easy to him." (For more from Donna, tune into E! News tonight, Sept. 23, at 11 p.m.)

But Mama Kelce is definitely preparing herself for how intense the show promises to be. Grotesquerie—also starring Niecy Nash-Betts, Micaela Diamond, Courtney B. Vance and Lesley Manville—follows Niecy's character Detective Lois Tyron investigating a series of heinous crimes that have unsettled a small community. She teams up with Micaela's nun character and the two begin to string together clues but are faced with more questions than answers.

While Travis' role is being kept under wraps until the show premieres, the 34-year-old definitely had his fair share of fun on set, despite the scary plotlines.

"This is what happens when WINNERS link up," Niecy shared on Instagram in May, alongside a video of her and Travis on set. "@killatrav Welcome to Grotesquerie!"

As Travis said in the video, he was excited about "jumping into new territory."

And the fun continued when the Super Bowl champ got a special dance lesson from Niecy, joking on Instagram in May, "Don't be fooled by the video…. We are working hard for @ryanmurphyproductions In between shots is another story."
