Jessica Simpson is ready to love herself forever.

On July 10, the “Sweetest Sin” singer shared a birthday message that spoke to patience and purpose.

“Oh lil Mrs 42 look at you leanin’ into the moonbeams to recharge and radiate a purposeful glowing heart,” she wrote on Instagram, along with a photo of herself posing in a black cutout cocktail dress. “I’m proud of my faith, strength and resilience over the past 4 decades.

She said, “Everything I have ever done in my life has made turning 42 extremely exciting. Because I understand what it means to be inside DETERMINED PASSION.”

Jessica said she knows herself well and loves the person she has become “very much.”

“I understand my purpose, and I must admit that ladies as well as gents, I’m equipped to confidently waltz through every dream I possess,” she said. “I feel humbled and honored that I can finally call myself my best friend.”
