Step Brothers actors Will Ferrell and John C. Reilly join Snoop Dogg on stage

Will Ferrell and John C. Reilly surprised Snoop Dogg with a birthday serenade onstage in Los Angeles on Saturday, 21 October.

In a backstage clip, the Step Brothers co-stars wheel out a three-tier cake for the rapper, who uses the candles to light a joint.

The pair led the crowd in singing “Happy Birthday” to Snoop, who blew out the candles.

Reilly and Ferrell also performed a rendition of “Boats ‘N Hoes,” a song they sang as Brennan and Dale in Step Brothers, and also joined Snoop for his 1994 hit “Gin and Juice.”
