Elle King, Pregnant with Second Baby, Hopes for a 'Big Family': 'I Want So Many Kids' (Exclusive)

Elle King is ready for a whole family of baby outlaws!

The country singer, 35, announced on Monday, Sept. 23, that she and her partner Daniel Tooker, 34, are expecting their second son together.

"I want so many kids," King, who shares 3-year-old son Lucky with Tooker, told PEOPLE exclusively in a recent interview. "I just want a big family."

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, who just released her latest single, "High Road," recently confirmed to PEOPLE that after separating 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."

The family is based and Tennessee and recently relocated — and now have more room for their new addition.

"We're starting fresh. We just bought a really gorgeous new house in the mountains of Nashville," she said. "It's happy, it's beautiful. I'm very happy, I'm very content, which is nice, and I don't know if I've ever really felt that, so it's a blessing."

And King also recently told PEOPLE that her son, whom she welcomed after suffering two previous pregnancy losses, got her through a difficult time earlier this year.

"He's so sweet. He's my best friend. I love him to death, and I just want want to give him the world. He makes me laugh, and he's just so curious and confident and smart. He loves Hot Wheels and cars just like Mommy, and he loves dinosaurs and wants to learn everything and loves playing music. He's the sweetest, best little boy. Such a blessing to me — and he's just my biggest driving force."
