Why has Michelle Obama shared a note about Stacey Solomon?

Stacey Solomon has said that she "can't stop laughing" after Michelle Obama shared a message about her on Instagram.

The former US first lady posted a collection of notes praising healthcare workers on social media as the world grapples with the coronavirus pandemic.

One of them was from the child of an NHS nurse who urged her mother to "get some sleep, relax and let Stacy (sic) Solomon get you giggling".

Solomon later posted on Instagram: "So many of you are tagging me in this.

"Me and Joe can't stop laughing that I'm on Michelle Obama's grid.

"I'm 100% sure the queen has no idea who I am but it has made my day nonetheless."

Obama had shared the handwritten note to the nurse alongside a message urging people to let healthcare workers know "if you're feeling grateful" for their work.

"From our medical providers and hospital staff to our grocery, transit and delivery workers, so many extraordinary people are putting their lives on the line to get us all through this moment," she said.

"Let's take the opportunity to tell them and their families that we see their sacrifices and we're behind them.

"A handwritten letter, an Instagram post, or a simple 'thank you' text can go a long way in letting someone know just how incredible they are and how much you appreciate what they're doing."
