Zac Efron is definitely faithful in Dylan Efron's chances of winning The Traitors.

In fact, the High School Musical alum recently revealed what he really thinks about his little brother competing on the Peacock reality series' upcoming third season.

"I think Dylan's going to win," Zac exclusively told E! News The Rundown's Erin Lim Rhodes at the A Family Affair premiere June 13. "I hope he does, because he's so good at games. He always has been since we were kids. He's like the game master."

As it turns out, Dylan just has the universe on his side when it comes to competition.

"I don't care what game it is," the actor added of his sibling. "It can be a luck game like Yahtzee and he always gets Yahtzee on the first roll."

And it doesn't matter if Dylan plays the game as a steadfast Faithful or is chosen to be a treacherous Traitor.

As Zac noted, "If anyone can do this, it's him. I'm rooting for him."

Dylan's serious game skills aside, he's definitely going to have some stiff competition when he enters the castle.

As Peacock announced earlier this month, the 32-year-old will be joined by a star-studded cast of quick-witted celebrities and reality TV stars hoping to win a cash prize of up to $250,000 by mastering challenges and secretly eliminating fellow contestants one by one.

Joining the season three cast are Vanderpump Rules' Tom Sandoval, The Real Housewives of New Jersey's Dolores Catania, Summer House star Ciara Miller, Real Housewives of New York City alum Dorinda Medley, The Real Housewives of Potomac alum Robyn Dixon and The Real Housewives of Dubai's Chanel Ayan.

Also headed to the Scottish Highlands are Selling Sunset's Chrishelle Stause, Bachelor Nation stars Wells Adams, Gabby Windey and Danielle Reyes and Survivor alums Tony Vlachos, Jeremy Collins, "Boston" Rob Mariano and Carolyn Wiger, just to name a few.
