The Great One has a case of Bieber Fever.
Wayne Gretzky, who held his fantasy camp in Las Vegas this week, attended Justin Bieber's concert there Friday with his wife, Janet, and daughter Emma.
Gretzky gave Bieber, a fellow Canadian, an Edmonton Oilers jersey, which the pop star wore on stage during the show at the MGM Grand.
The jersey had No. 6 on the back with Bieber's name.
Emma and Janet also got to meet Bieber, who is on his Purpose World Tour, evidenced by two photos on Janet Gretzky's Instagram account.
The Oilers team Instagram account posted a photo of Bieber wearing the jersey.
