Footage of First Lady Melania Trump reminding President Trump to place his hand over his heart during the National Anthem exploded on social media Monday morning.

In the clip — coming from Monday’s White House Easter Egg Roll — the First Lady and Barron place their hands on their hearts just as the Marine Band begins to play, yet Melania nudges POTUS’ right hand with her left just seconds later.

WATCH:

Twitter immediately took notice.
