According to Metro.co.uk, the controversial fighters shamed the boxing game with their ugly press conference brawl following Chisora's defeat to Vitali Klitschko in February 2012.
They settled their differences in the ring five months later, with Haye winning a breathless bout in London, the report said.
Now, the sworn enemies seem to have become best buddies, enjoying the NFL match between Minnesota Vikings and the Pittsburgh Steelers alongside Haye's manager and trainer Adam Booth and Entourage actor Jeremy Piven, the report added.
Haye posted a picture posing with the stars, while tweeting that there was no security needed that night.
Haye was supposed to be fighting unbeaten British heavyweight Tyson Fury this weekend but pulled out of the bout, which has now been rescheduled for February, after cutting his eye in sparring, according to the report.
