Sharna Burgess is in mommy bliss!

The professional dancer, 37, shared an adorable photo of her cuddling with her newborn son, Zane Walker, showing his face for the first time.

In the snap, Burgess peacefully closes her eyes as the infant, whom she welcomed last month with Brian Austin Green, sleeps on her chest.

"Food Coma… Zane obviously. Cos I'm the food 😂," she joked in the caption.

Opening up about her experience of being a mom, she wrote, "I don't yet have words that can do this justice. I know I look at him and well up with tears at how cracked wide open my heart is and how deeply and unconditionally I love him."

"I know I'll never be the same again, ever. I realize I never knew love of this kind or capacity existed and it's beautifully overwhelming to process," Burgess continued.

Continuing to reflect on motherhood, she said she can "now wholeheartedly understand everything my mum has ever said to me about a mothers love being unlike any other. You know, that whole 'you'll understand when you have kids' thing parents say when they are fussing over you. I get it now."

"I will love him and worry about him until my last breath and beyond. Heaven is a place on Earth, and i found it," she said of life with Zane.
