Christina Aguilera Celebrates Fiance Matthew Rutler’s Birthday With a Stunning Pregnancy Throwback Pic

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.

"Birthday boy...," Aguilera wrote. "To a wonderful father, loving man and hardest worker I know."
