The pop star posted a sweet black-and-white photo of an embrace with her soon-to-be hubby kissing her forehead.

"Birthday boy ... to a wonderful father, loving man and the hardest worker I know," Aguilera wrote in the caption.

Aguilera and Rutler met in 2010, following her divorce from music producer Jordan Bratman after six years. During her time filming Burlesque, the pop singer met her new beau on-set and the two became inseparable.

Rutler proposed on Valentine's Day in 2014, and the couple welcomed daughter Summer later that year.
