Pop singer Demi Lovato wowed all those who attended 106.1 KISSFM's Fall Ball in Seattle on Nov. 14, when she sang a cover of Adele's "Hello" and nailed it.

According to E! Online, the 23-year-old star also performed her biggest singles, including "Cool for the Summer," "Heart Attack" and "Neon Lights." The star then took a break from her own tunes to treat her fans to a version of Adele's record-breaking single.

While Lovato is known for her strong vocals, Adele's songs are considered challenging because of the British star's own powerhouse skills. However, Lovato received a lot of praise for her performance from fans on social media, including singer Becky G, who was also a performer at the Fall Ball.

Becky G took to Twitter to complement the show, even prompting a response and retweet from Lovato.

"@ddlovato never fails to blow my mind. Wtf just happened. Wow. One of my favorite live vocalist to see in concert," Becky G tweeted.

Lovato replied soon after with, "@iambeckyg you are so sweet!!!! Thank you girl.. Wish I could've given you a big hug last night!!"

Media personality Perez Hilton also shared his take on the "Confident" singer's performance on Twitter, which Lovato then retweeted.

Becky G and Hilton weren't the only ones amazed by Lovato's take on Adele. Several other fans tweeted they had their doubts about Lovato taking on such a powerful song, but they were amazed once she was done.

Fans may get to see the singer cover other popular songs when she hits the road for her joint tour with Nick Jonas, called "The Future Now Tour," next summer.
