First lady Jill Biden and second gentleman Douglas Emhoff unintentionally created the first viral moment of President Biden's second State of the Union address.

Ahead of the speech, the first lady received a warm reception when she walked into the House Chamber, but an even warmer one from Emhoff. 

Both she and the second gentleman were seen greeting each other with a kiss on the lips.

Many called the kiss "weird" while others joked that "COVID is over."

"Is this... normal?" Daily Wire senior editor Cabot Phillips wondered. 

"Cheek is fine. Or a hug. This is odd considering they both knew the cameras were on them," Fox News contributor Joe Concha tweeted.

Conservative commentator Kelsey Bolar joked, "plot twist."
