Pregnant Elle King Proudly Shows Off Her Baby Bump in Chic Black Tweed Outfit: 'Growing Our 2nd Baby'

Elle King is getting closer to meeting baby No. 2!

On Wednesday, Oct. 9, the Grammy-nominated singer, 35, shared a sweet carousel on her Instagram as she celebrated five years of meeting her partner Daniel Tooker. The couple is already parents to 3-year-old son Lucky Levi, with a second baby on the way.

King shows off her baby bump, cradling her stomach while posing in a black, tweed mini dress, black tights and black loafers. In another selfie, the "Ex's and Oh's" singer smiles at the camera held above her head as her other hand rests just below her bump.

After first announcing her pregnancy onstage during a Baby Daddy's Weekend tour stop in Tulsa on Sept. 22, King shared the happy news on Instagram the next day, sharing a video from their sex reveal before captioning another post: "I am so happy. Thank you for all the love and support as [Tooker] • Lucky • and I grow our family #TableForFour."

King recently confirmed to PEOPLE that after the couple separated last year, she and Tooker had reconciled for Lucky.

"We're back together," she previously told PEOPLE. "We had to grow. I don't know. I'll try anything twice."

King added of Lucky: "He's definitely brought me and his dad back together just because, what are we doing? We have everything that both of us have ever wanted right here. Let's put our weapons down. Come on. This is it. This is life. It doesn't get better than this. This is worth trying. This is worth wiping a slate clean. This is worth all the effort in the world. My family, this is what deserves all the energy and effort."
