He clicked his heels, cradled Swift in his arms, and mimed putting makeup on her face during a well-rehearsed skit, hitting all his marks as a member of her supporting cast.

While tens of thousands of fans in London's Wembley Stadium screamed their approval, none had shelled out money for tickets to see Kelce.

His cameo was the mere cherry on top of Swift's monumental career achievement: She'd set an attendance record for the venue and generated an estimated $1 billion for the UK economy .

Not that Kelce seemed to mind playing second fiddle.

In fact, he said it was "an honor" to dip his toe into Swift's world, casting himself as a superfan who got luckier than most.

"You can do no wrong when Taylor's onstage," Kelce said on his podcast .

"She's the best to do it." Kelce is a star in his own right, an athlete on track for the NFL Hall of Fame.

Yet Kelce's reported net worth is dwarfed by Swift's multibillion-dollar fortune , and this summer's headlines about his return to football can't resist shoehorning in a mention of his and Swift's recent wedding .

Off the field, Kelce's prestige is not threatened by Swift's success but is perhaps even bolstered by it.

He belongs to a new wave of secure Hollywood husbands: male celebrities whose enthusiastic endorsement of their high-earning wives makes them more endearing and, crucially, more bankable.

Taylor Swift's now-husband, Travis Kelce, joined her in a supporting role during The Eras Tour stop in London.
