Conor McGregor and his fiancée don't seem worried one bit about the UFC superstar's junk allegedly making its debut on social media this week ... with the two enjoying their time together on a yacht -- and Dee Devlin specifically looking happy as could be.
Many wondered if Devlin -- who got engaged to McGregor in 2020 -- would be livid over the recent drama surrounding her man ... especially after rapper Azealia Banks claimed he slid into her DMs with "unsolicited" nude pics.

He was also spotted cozying up with another woman on a beach this week .
