Then, DeGeneres surprised guests by bringing out Cooper — this was in the midst of the two women taking a selfie. Naturally, the War Dogs star brought up the time he visited the White House for the State Dinner in 2014.

"I had just done American Sniper, and I only have one tuxedo, and it didn't fit," Cooper said. "I was so nervous it would rip, so I decided at the last minute to 86 the underwear."

Hmm, before the Obama administration, we would not have ranked this as one of the best topics of conversation with the president's wife. Not so today.

"Because if it should rip, it's much better to not have underwear on," DeGeneres joked.

"It's better for us," Obama quipped. "It's good for us, right ladies?"
