John Cena spent his wrestling career wearing custom jerseys and baggy shorts ... but the future WWE Hall of Famer is sporting a different look for his new movie -- high heels, a short skirt and tights!!
The 45-year-old is currently in Melbourne, Australia shooting his upcoming comedy, "Ricky Stanicky" ... and by the looks of it, he's going all-in on the title role.
Cena has always maintained an incredible physique since becoming a WWE Superstar ... and it was on full display while filming, as he showed off his swole legs and balance.
