"Bring that belt with you when you come to my house", said Cormier, who has vowed to retire when he turns 40 in March.
Back in July, Cormier scored a stunning first-round knockout win over Stipe Miocic to claim the heavyweight title, becoming the first man to hold the heavyweight and light heavyweight titles simultaneously. He also now holds the light heavyweight championship and was presented with two title belts after the fight.
Lewis struggled free to survive the first stanza, although Cormier picked up where he left off in the second round, nullifying Lewis' fabled punching power by securing yet another takedown before choking out the challenger, who in truth had offered little threat throughout. In the second round, Lewis opened with a hard combination, but Cormier managed to avoid his powerful right hand.
UFC president Dana White has said he wanted a Lesnar-Cormier bout signed for next year, a showcase that would surely be the biggest ever for heavyweights.
As Daniel Cormier prepares to defend his UFC heavyweight title for the first time, all the talk surrounds a future fight with Brock Lesnar.

Lewis had a size and reach advantage, but Cormier set the tempo and took Lewis down at will before submitting him in the second round.
But then Lewis started stringing together victories and developing a cult following on social media, and when he rallied in the final seconds to defeat Alexander Volkov at UFC 229 to earn his ninth win in his last 10 appearances, the Houston native established himself as a legitimate title contender.
In between rounds, Cormier's corner instructed him to do the exact same thing and exhausted the Black Beast out. He secured top control on Lewis where he landed short shots to Lewis.
He just needs one punch, and even if we've said that before all-too-recently, that doesn't mean it's impossible.
We're definitely going to miss Cormier when he hangs up his gloves, which will likely take place next year.
