And lastly, I'd do something that was a little terrifying for me, which was to sing, making an appearance on the late-night host James Cor-den's hilarious "Carpool Karaoke" series, the two of us circling the South Lawn in a black SUV. We belted out "Signed, Sealed, Delivered I'm Yours," "Single Ladies," and finally-the reason I'd signed on to do it in the first place-"This Is for My Girls," with a guest appearance from Missy Elliott, who slipped into the backseat and rapped along with us.

I'd practiced diligently for my karaoke session for weeks, memorizing every beat to every song. The goal was to have it look fun and light, but behind it, as always, was work and a larger purpose-to keep connecting people with the issue. My segment with James had forty-five million views on YouTube within the first three months, making every bit of the effort worth it.

Today marks the 4th anniversary of the passing of Queen Elizabeth II, and she is missed more than ever, as this would have been the year of her 100th birthday. I believe it’s right on this day to remember her extraordinary life of service to the nation and the Commonwealth, which she served with grace and dignity until the very end. She was so much more than a Queen, she was the steady heart of the nation and a symbol of strength for the entire world.
