Kelly Clarkson leaves cafe customers spellbound with a breathtaking surprise a capella performance

It's no surprise to any fan that Kelly Clarkson is a vocal powerhouse. Recently, she surprises a few people in Los Angeles by singing two tracks off her upcoming album "Chemistry," inspired by her ex-husband. What's even better was Clarkson took part in not one but two acapella flash mobs in the city. The 41-year-old showed off her incredible vocals along with talented singers in a courtyard outside of Sweetgreen and inside a Blue Bottle coffee shop, reported PEOPLE.

The host of "The Kelly Clarkson Show" sang the songs "Favorite Kind of High" and "Me" to surprise LA shoppers before a group of bystanders turned background singers joined in. Viewers cheered them all on after each goosebumps-inducing rendition of her songs. Clarkson shared the videos of the performances on her Instagram account. “I would like a vanilla latte,” Kelly joked to the barista after singing "Me."

“Imagine having lunch, and Kelly Clarkson starts a flash mob behind you.” @rheenabettes shared in the comments section, “You can just flat out SING, girl!” @andrei_long3n said, "OMG! Wish I was there in person witnessing all those vocals!"

Clarkson's upcoming album is titled "Chemistry" for a reason. “I never really connected [to anyone] before my ex-husband,” she said in May in an interview with Nancy O’Dell on TalkShopLive. “And I never connected with anybody like that. I'd never felt that. That kind of chemical that level of just chemical reaction, I just never felt that and I remembered the first time we even met, I was like, 'Woah.' I just felt something."

Finding that spark and chemistry doesn't always mean that it can be a fairytale. "And then it can go very poorly, chemistry. You can have amazing chemistry with somebody who you really shouldn't be with, you know. Not that one person is good or bad, whatever. It's just not a healthy environment. I just feel like chemistry is a beautiful and amazing thing, but it's powerful for the good and the bad. Makes you do stupid stuff," the "American Idol" star shared.

Clarkson and her former husband, Brandon Blackstock, were engaged in 2012 and tied the knot in October 2013 in Tennessee. The couple also share two children, River and Remington. After nearly seven years of marriage, the pair decided to part ways in June 2020. While talking about co-parenting, her kids splitting time between parents, she said, “It was so weird because you’ve always had a kid there, and then all of a sudden, you’re alone." She added, “At first it’s weird and then you’re like, ‘OK. I can do things,’ It’s kind of incredible. You do get a little 'me' time,” reported TODAY.

However, "The Voice" coach believes in her children and is confident they will cope with anything life throws at them as they grow up. “I think I am my mother’s child and I’m raising very independent children,” she said. “They will be out the door as soon as they are able and capable. They are very independent and I was the same way.” When she has to let them go, she thinks she will be okay because “by that point, I will have raised someone that I — if I’m doing my job — feel like, I trust you. I trust the decisions you’re going to make. I trust what’s going to happen.”
