Christina Aguilera celebrated her man's birthday in serious throwback style.
The pop star took to her Instagram stories on Thursday to celebrate fiance Matthew Rutler's special day, sharing a gorgeous throwback photo from her 2014 pregnancy with daughter, Summer Rain.
The black-and-white image, adorned with pink hearts and arrows pointing to her baby bump, features Aguilera lying on her back in a sheer white v-neck dress while a shirtless Rutler leans in for a kiss. It was the same photo from her shoot with Vmagazine, one that also featured the 37-year-old singer naked with her bump on full display.
The former Voice coach also shared a touching shot of her and Rutler in a sweet embrace while he kisses her forehead.
"Birthday boy...," Aguilera wrote. "To a wonderful father, loving man and hardest worker I know."

Rutler appeared grateful for all the birthday love, sharing a clip to Instagram of a 3-year-old Summer gifting him with a box of sweet treats.
"For your birthday," the little girl adorably stated, as she shoved a box toward her dad.
"For more birthday?!" Rutler asked, incredulous.
"Open it, Daddy!" she replied.
Aguilera met Rutler on the set of Burlesque in 2010 and started dating shortly after her divorce from Jordan Bratman. Her and Bratman have a 10-year-old son, Max, together.
