In an exclusive conversation with PEOPLE about returning to American Idol for the show’s season 21 finale on Sunday, the country musician, 55, also chats about attending Taylor Swift’s Eras Tour last weekend with his wife, Nicole Kidman.
“We had the best time,” Urban says. “It’s an amazing show. I knew it would be, but it’s a whole other level. I mean, she’s absolutely at the top of her game. This tour is just the best of the best.”

“The Fighter” musician documented his time attending the tour at Philadelphia’s Lincoln Financial Field, where he sat in the VIP section of the crowd, in a TikTok video.

In the clip, Urban and Kidman, 55, can be seen rocking out to 1989‘s “Style” and the beginning of “Blank Space.” He captioned the post, “We love ya @TaylorSwift.”Swift, 33, kicked off her highly anticipated Eras Tour in Glendale, Arizona, last month. The event is scheduled to run through Aug. 9, when the final performance will take place at the SoFi Stadium in Los Angeles, California.

During the show, which runs for three hours and 13 minutes, the singer captivates her audience with a massive, career-spanning 44-song set list that includes nods to each of her respective album eras, including her latest LP, Midnights.
