Conor McGregor has only fought one UFC bout since 2016, but he's apparently ready to take part in some celebrity fighting.

McGregor and Bieber seemed to bond back in April over Bieber's apparent Irish heritage. However, neither of them seem to have any connection to the men they called out over social media.
Cruise might have a decent shot against Bieber after doing his own stunts in action movies throughout his Hollywood career, but Wahlberg—even if he is in good shape—would likely have a rough time against the former UFC champion.
