Taylor Swift and Travis Kelce are each other's biggest cheerleaders.

The Life of a Showgirl singer's new docuseries The End of an Era dropped on Friday (December 12) and the two-part premiere featured a sweet phone call-turned pep talk between Swift and her beau Travis Kelce. The Kansas City Chiefs tight end was hyping up his now-fiancée as she prepared to take the stage at Wembley Stadium in London for her Eras Tour with surprise guest Ed Sheeran, per Page Six.

"How are you guys so good? You can just do a little in-the-backroom rehearsal and then go do this live in front of everyone," Kelce said.

The "Fate of Ophelia" hitmaker threw the praise right back at the "love of [her] life," responding, "How do you remember 36,000 plays that are all tactical missions and then just go do it? It's the same. It's basically the same job. I've got songs to remember, you've got plays to remember."

The couple, who got engaged in August, then commiserated over their schedules not allowing them to be together at the time.

"I want to be there!" Kelce said, before Swift quipped, "Why do you have to be in the NFL?" and wished him a "great practice" with his team. She then noted how much the conversation meant to her, saying, "I love you so much. Some people get a vitamin drip, I got this conversation."

The London show was her first after being forced to cancel her three concerts in Vienna, Austria, following a foiled terrorist attack planned for the venue, so she was nervous about how the night would play out. Swift reflected on the dark chapter of the tour in The End of an Era and how they "dodged a massacre situation," while explaining how she felt like she was "skating on thin ice" in her return to the stage.

The first two episodes of The End of an Era docuseries are now streaming on Disney+.
