Kelly Clarkson is back in the game!

Two months after giving birth to her second child, the 34-year-old singer is showing off her stunning vocals with an acoustic cover of Otis Redding's "These Arms of Mine." Clarkson took to Facebook Live on Monday to broadcast the performance straight from her home and to tease a big announcement coming on Friday.

Clarkson explained that she would be singing live on Facebook each day this week, performing fan-requested covers. "I picked these four songs because these four artists that did these songs have something in common. That's my hint," she teased, pointing the audience to Friday's big reveal. "It's the coolest announcement for me as an artist and I don't want to ruin it, because I'm the person to tell you on accident."

For what it's worth, the American Idol champ also made sure to point out that Monday's song had been featured on the Dirty Dancing soundtrack.

Monday's low-key performance marked Clarkson's first time singing live since going on vocal rest earlier this year.

"I haven't been able to sing in forever," she said, "'cause I was on vocal rest, which sucks. So, if I get carried away and do all my white girl runs, I'm sorry. I'm just excited to sing!"

In February of last year, Clarkson opened up to ET Canada about temporarily losing her voice after giving birth to her first child, daughter River Rose, in 2014.

"Afterwards was the part where I literally had a moment where I cried and drank wine all day," she admitted. "I was like, 'Oh, God, I'm not going to be a singer anymore!' I was bawling to my husband and like, completely hammered, just going, 'Oh my God, it's over, I don't know what I'm going to do. I guess I could do more charity work.' Like, I didn't know what I was going to do."

Perhaps she suffered a similar vocal scare after welcoming son Remington Alexander in April?

"Months ago, I sounded like crap because my voice was so tired," Clarkson said during Monday's livestream.

We thought she sounded great during her two appearances on the final season of American Idol! The singer broke down in tears during an emotional performance of "Piece by Piece" on Feb. 25. Then, on the epic April 7 finale, Clarkson popped up in a pre-recorded segment to deliver a medley of her biggest hits.
