According to the publication, the duo were seen drinking wine at New York City's Kingside restaurant on Thursday, after Hamm hosted the Brooklyn Black Tie Ball.
"They seemed to really be enjoying each other’s company," a witness told the outlet of the "low-key" date that reportedly lasted for about two hours.
It’s not the first time Hamm, 46, and Johnson, 28, have been spotted together. Apparently, the potential couple were spotted together back in April at Elton John's 70th birthday party.
Reps for Johnson and Hamm did not respond to Page Six's request for comment. We guess we'll just have to wait and see how this random, unexpected report turns out!
