Miles Teller was reportedly assaulted during a lunch date with his wife in Maui, Hawaii on Wednesday - due to a dispute over the bill for his wedding.
Law enforcement sources tell TMZ the actor was in the restroom at the Monkeypod Kitchen restaurant when a man confronted him and punched him in the face.
During an altercation that followed, Teller threatened to press charges. He and his wife, Keleigh, then quickly left the restaurant.
Sources claim the man was a wedding planner who accused Miles of owing him $60,000 (£42,300) for services he provided at the actor's Maui wedding in 2019.
Police officials have confirmed the incident occurred on Wednesday evening. No one was arrested but officers are investigating.
Teller, who has also been joined in Maui by his Divergent co-star Shailene Woodley and her fiance Aaron Rodgers, has yet to comment on the fight.
