Now, some reports claim that Johnson made a big decision in order to stay close to his new girlfriend: ditching his plans to attend business school in Pennsylvania.
But a friend of the former football player tells PEOPLE that's simply not true.
Though Johnson had planned to attend the prestigious Wharton Business School's MBA program this month, he "decided against it," says the friend. "There were a lot of factors that went into his decision. Jessica supports him in whatever he wants to do. He has a lot going on."
The same can be said for his girlfriend. Simpson, 30, recently appeared on Entourage, getting great reviews for her shrewd cameo, in which she calls agent Ari Gold (played by Jeremy Piven) "an a--hole" when he tries to keep her as a client by wooing her with a new dog to replace her late Maltipoo, Daisy.
There's also talk that Simpson is in the running to become a new American Idol judge, and she's got a new VH1 project in the works.
"She is in pre-production for a new show," a TV insider tells PEOPLE. "It will be the next step to her VH1 series, The Price of Beauty."
