The actor, 58, announced on Instagram Tuesday that he popped the question to his longtime friend-turned-lover, Josie Hart.
Before Underwood began dating Hart, the actor was married to Desiree DaCosta.
The pair welcomed three children together — sons Paris, 25, and Blake, 21, and daughter Brielle, 23 — during their 27-year marriage before announcing their split in a joint statement in May 2021.
While it’s unclear exactly how long Underwood and Hart have been dating, the couple’s friends were thrilled by the engagement announcement and shared their congratulatory wishes in his comments section.
