Squid Game: Mel B, Dylan Efron and Tristan Thompson join new celebrity cast

Spice Girls' Mel B is set to compete in a new 'Squid Game' season against a total celebrity lineup.

Netflix has announced the cast of the forthcoming 'Squid Game' spin-off game show 'Squid Game: The VIP Challenge'.

In the new series, seven celebrity contestants and one former 'Squid Game' player will compete in the "already stressful, deeply unpredictable and downright diabolical competition".

In a post to Instagram, the Spice Girls singer shared the official announcement video with the caption, "Squid Games are about to get really Scary!"

The star line-up also includes Ryan Serhant from Owning Manhattan; NBA champion Tristan Thompson; content creator Kristy Sarah; Real Housewives of Atlanta's Kim Zolciak; Hannah Godwin from The Bachelor universe; and Dylan Efron, Zac Efron's brother. The final contestant is Viper, a player from 'Squid Game' season 2 who was voted in by fans to return to the competition.

Viper said “It’s been positively overwhelming seeing all the support" from the fan vote.

He told Tudum, “I think that people recognized that I’m genuine and found a way to advocate for my best interests without losing my sense of self.”

As for Season 3, he pans to cause total "chaos". And don’t underestimate him – he’s got experience now, and knows even a tiny slip-up (like dropping a ball in a game of catch) could get him eliminated. “Every decision now gets the microscope treatment,” he adds.

He hasn’t met the rest of the Season 3 cast yet, but Viper has some thoughts on how they’ll react to seeing him re-enter the 'Squid Game'.

“I feel like they’ll either come for me… or try to team up, because I’m fierce competition," said.

Netflix has not yet announced the premiere date for 'Squid Game: The VIP Challenge'.
