The segment began with Fallon once again portraying Sara as she welcomed her friend Addison (Cena) to the show after the pair had spent a long time apart from each other.
"I have to say, you look really different," Fallon said to the professional wrestler who was seen wearing a wig, makeup and a sleeveless dress that highlighted his bulging muscles. "Yeah, I had a little bit of a growth spurt. My mom said I'm going through some changes," Cena replied.
The duo, after discussing their crushes, began to rehearse a dance routine set to Bruno Mars' "Finesse." Cena and Fallon could hardly contain their laughter after Cena lifted up the comedian during their dance.
Cena and Fallon were also interrupted by stepdad Gary (A.D. Miles) and participated in a "Ew!" lightening round.
Cena was hand on The Tonight Show to promote WrestleMania on April 8, his new comedy film Blockers on April 6 and the Nickelodeon Kids' Choice Awards on March 24, which he is hosting.
