Derek also appeared in the photos, only he kept it quite casual in a “The Purge”-esque mask and a snapback cap.

Ellen and Derek got engaged a few months after coming public about their relationship last February.

The two recently dropped a dreamy photoshoot on Instagram which many netizens speculated to be a prenup shoot .

Based on Ellen’s Instagram updates, Derek has also been spending a lot of time with her son, Elias . —Margaret Claire Layug/JCB, GMA News
