The Maroon 5 singer was so elated to see his model fiancée slinking sexily on the runway at Wednesday night's Victoria's Secret Fashion Show that he gave her a standing ovation.
The 34-year-old sat front row and was beaming as he watched the 24-year-old strut her stuff wearing giant angel wings and Victoria's signature skimpy underwear line during the show, which took place at New York's Armory.
But the best interaction between the two came at the end of the program during the final "Snow Angels" Section.
When the Namibian-born beauty got to the end of the glitter-filled catwalk where her future hubby was seated with Maroon 5 bandmate James Valentine and Lady Antebelum's Charles Kelley, she gave her man a sexy smile and shout-out in the form of a quick fist pump.
Levine returned the favor by jumping to his feet and cheering his ladylove on while Prinsloo raised her arms in the air in giddy appreciation.
The couple met about 16 months ago after The Voice judge split from longtime girlfriend Anne Vyalitsyna and, after a brief breakup, got engaged this past July.
