“I am so happy and excited and still can’t believe it’s true!” Prinsloo told ET Canada. “It was a one-knee thing! It was serious, it was very old school.”

Adam and Behati have been a couple since May 2012, and they have broken up for a short time earlier this year.

The reconciliation was completed with an engagement as Levine popped the question last weekend.

The couple hasn’t yet started wedding planning, “just celebrating with our friends and family at the moment.”
