Williams Racing drivers Alex Albon and Logan Sargeant got a special behind-the-scenes tour of T-Mobile Arena - home of the NHL's Vegas Golden Knights.
Two two F1 stars were greeted by some cabaret dancers sporting team colors as well as the team's mascot, Chance the Gila monster.
Inside the locker room, they found two customized jerseys hanging up - both complete with their racing numbers.
But it was after they put these on that Albon and Sargeant realized the Florida-born driver could get into a bit of trouble.
You see, Sargeant is a die-hard fan of the Florida Panthers - the team that the Golden Knights beat to win the Stanley Cup this year.

Albon quipped 'You're gonna get a lot of hate for this' - which Sargeant agreed with.
After that revelation, Chance the mascot started motioning to kick Logan out of the locker room before posing for pictures.
For pics, Chance put Sargeant's head inside his mouth - leading to laughs breaking out throughout the room.
Sargeant will hope that he can perform at the inaugural Las Vegas Grand Prix better than his beloved Panthers did in Sin City earlier this year.
After getting battered 5-2 and 7-2 in Vegas, the Panthers won Game 3 by a 3-2 score in overtime.
But the Golden Knights returned the favor with a 3-2 win the next game and sealed the Cup with a 9-3 demolition in the decisive Game 5.
It's the first Stanley Cup in Golden Knights history - while the Panthers are 0-2 in the cup Finals all time.
