The Commas star, who split from his fiancee Ciara last year (14), was recently linked to the busty model - and she appeared to confirm the speculation by having his name tattooed on the side of her hand.
However, on Tuesday (27Oct15), Future dismissed reports he is getting serious with Chyna after a month of dating, declaring he isn't even in a relationship.
He simply posted, "Single & focusing on what makes me happy", before adding of the online gossip, "U kno I dnt f**k wit no rumors (sic)..."
Chyna has yet to comment on his remarks or her new ink.
Neither star is a stranger to relationship drama - the rapper previously took issue with Ciara flaunting her new romance with American footballer Russell Wilson in front of their young son, Future Zahir, while Tyga reportedly left Chyna for Kim Kardashian's teenage sister, Kylie Jenner, last year (14).
