Dwayne 'The Rock' Johnson and mum sing Samoan kids' song on The Tonight Show

Last week Dwayne "The Rock" Johnson was on the Tonight Show where his mother stole the show and sang a song many Kiwis and Samoans may know.

While speaking virtually with Jimmy Fallon the actor's mother joined the pair when Fallon asked if his mother played the ukulele, the actor said, "Oh yes," and then called off-screen to his mother, "She's right here."

Ata Johnson stole the show immediately and showed off her ukulele skills.

After a few questions, The Rock then announced the pair will sing a song which Fallon seems to be delighted about.

Ata chooses to sing a classic Samoan kids song, Savalivali Means Go for a Walk.

The smiley mother and son duo then start singing.

"Savalivali means go for a walk, Tautalatala means too much talk. 'Ou te alofa iate 'oe means I love you, Take it easy fai fai lēmū" they sing.

The duo then performed an impromptu serenade for their host Fallon, who is thrilled.

"You just stole the interview. You're unbelievable! You are a superstar" he tells the 72 year-old.

He posted the video of them singing to Instagram saying "A career first ... singing with my mom @atajohnson on @fallontonight."

"Best part of all this is she's so happy doing this for Jimmy (whom she adores). So happy! I love it. Meanwhile I'm like "imagine if she was drunk", he wrote on Twitter.
