Earlier this week, Splash! star Tom released a YouTube video to fans, telling them he is in a gay relationship with a man.
"Come spring this year my life changed massively when I met someone and it made me feel so happy, so safe, and everything just feels great. And, well, that someone – is a guy," he said.
It has now been suggested in unconfirmed reports that the man 19-year-old Tom met in the spring is Dustin, who is 20 years his senior.
The Oscar award-winning director is a LBGT activist (Lesbian, Bisexual, Gay and Transgender) and the pair were spotted grabbing a coffee together in Hollywood last week.
A friend told The Sun: "He's besotted with Dustin. They love each other and aren't concerned what anyone says about age difference."
In Tom's five-minute video, he admitted he had never spoken out about his sexuality as there was no relationship to talk about.
However, he added: "It was always in the back of my head that something like that could happen, but it wasn't until spring this year that something just clicked. It felt right, and I was like, 'Oh ok'. My whole world just changed.
"Of course I still fancy girls, but right now I'm dating a guy and I couldn't be happier."
Reveal has contacted Tom's rep for a comment.
