The Pussycat Dolls star shared a series of sweet photos on Instagram showing her and former rugby player Evans, 35, celebrating her birthday in the sun.
In the first snap, the couple smiled for the camera while standing with their arms around one another in the sea against a dramatic rocky backdrop.
The second showed their footsteps in the sand on the beach, while the next two saw the pair apparently enjoying a low-key birthday celebration outside, sitting underneath a tree on a white blanket and then toasting one another with a glass of wine and a spread of food.
Scherzinger shared a “birthday prayer of gratitude” alongside the photos, thanking God for “the joy and overwhelming love” she has received from “family, friends and so many around the world.”
“Thank you God for another year around the sun,” she wrote. “For a new day, fresh breath in my lungs and my heart beating stronger than ever, I am so grateful.
“Thank you for your grace and this unexpected gift of time. Thank you for the joy and overwhelming love I am able to receive today from family, friends and so many around the world. .
“Thank you for being so good to me and for never giving up on me, you’ve shown me the true meaning of love, happiness & peace, and I am eternally grateful.”
She signed off with “Your little Nicole xo” before adding: “It’s so important to take time to reflect on how fortunate and blessed we are, now more so than ever. Hold on, don’t lose faith. God is good.”
Scherzinger and Evans started dating last year after meeting during filming for The X Factor: Celebrity, on which the singer served as a judge and the sports star appeared as part of boy band Try Star.
