Adam Levine and Behati Prinsloo stepped out in style at the 12th annual Breakthrough Prize ceremony on Saturday, April 18. Levine, 47, sported a classic black suit with a pastel blue button-down for the occasion on, while, Prinsloo, 37, looked radiant in a one-shoulder vintage grey Plein Sud gown. For glam, the supermodel wore her blonde tresses in loose waves that cascaded down her back. The Maroon 5 frontman and Prinsloo have been married since 2014, during which period they welcomed three children. The couple are one another's biggest fans.
