Foxx, 45, adamantly denied the dating reports Tuesday.
"[The rumors] are one hundred percent not true," Foxx told Entertainment Tonight. "In fact, it's quite hilarious because we simply danced at a charity event along with a lot of other people."
"I only know they are friends," Holmes' rep told Extra.
Holmes, 34, and Cruise divorced last year. There's also rumors that she dated her "Mania Days" costar Luke Kirby earlier this summer.
