Mumford & Sons singer Marcus Mumford became a bit of a viral star after he was caught on camera yawning during Prince Harry and Meghan Markle‘s royal wedding back in May—and no one was more surprised than his wife, Carey Mulligan.

On Thursday, October 25th’s episode of Jimmy Kimmel Live!, the Oscar-nominated actress recalled her husband’s yawn seen around the world, explaining that she and Mumford never imagined anyone would be watching them among the wedding’s 600 guests.

So just why was Mumford, 31, so sleepy? Well the way Mulligan tells it, the two “hustled to the church” to watch the royal couple tie the knot at St George’s Chapel at Windsor Castle, but ended up waiting around for nearly two hours before the event began. “It was lovely and atmospheric and beautiful, but kind of a long time,” she said.

The funny thing is, Mulligan was worried they were being filmed—and even warned Mumford about it before his viral moment. “There were cameras everywhere,” she recalled. “We were chatting with our friends and my husband was like, ‘Give [me] a kiss, babe.’ And I was like I’m not going to give you a kiss, there’s cameras. He’s like, ‘George Clooney’s here, Elton John is here, the Beckhams—they’re not filming us.’”

Of course, there is an upside. As Kimmel joked, “Marcus could probably parlay that into a coffee endorsement or something.”

Meanwhile, the Duke and Duchess of Sussex are currently on a 16-day tour through Australia, Fiji, Tonga and New Zealand—which includes a stop in Sydney this weekend for the closing of the Invictus Games, Harry’s annual sporting event for wounded, sick and injured veterans and armed forces members. The royal couple made headlines on Friday, October 26th when a plane they were flying in to Australia had to abort its landing in Sydney because another aircraft was on the runway below. It has since landed safely.
