Will Ferrell and John C. Reilly team up with Snoop Dogg to sing 'Boats 'N Hoes' on stage

Will Ferrell and John C. Reilly have teamed up with none other than Snoop Dogg to bust out one of their best hits on stage.

Ferrell invited Reilly to perform 'Boats 'N Hoes' at the Best Night of Your Life 2 benefit show the Greek Theatre in Los Angeles, according to Entertainment Weekly.

And audiences were in for another treat, as Ferrell invited rap legend Snoop Dogg to perform his own verse on the Step Brothers track.

Reilly then explained to everyone that Snoop's birthday was the day before.

"We're about to sing happy birthday to the greatest rapper in the world!" he said.

Not only did Ferrell and Reilly get the crowd to sing him a happy birthday, but they wheeled out a humungous three-tiered cake.

There were loads of candles on the big dessert and Snoop in true Snoop style lit a joint from one of the flames.

The rapper posted a video of the moment the cake was taken on stage and everyone sang along for him.

He wrote: "My brothers surprised me. Will and. John."

People magazine says Snoop then sang his hit song 'Gin and Juice' with Reilly and Ferrell to cap off the incredible team up.

If you thought that was the weirdest moment for Will Ferrell recently, you'd be mistaken.

The Step Brothers star appeared at the University of Southern California's Sigma Alpha Mu house and did a DJ set.

With his backwards cap and shades, Ferrell looked every inch the coolest man in the world as he was surrounded by people amazed that the actual Will Ferrell was doing a DJ set for them.

Of course, it could have been a lookalike, or even Red Hot Chili Peppers drummer Chad Smith, since the two share quite the resemblance when rocking the backwards baseball cap look.

Still, everyone at the party looking over would have seen what appeared to be Will Ferrell having the time of his life.

Ferrell's son Magnus is a student at the University of Southern California and he's explained why his famous dad rocked up to DJ at a frat party.

“Me and my roommate, we both DJ, and I was like, ‘hey, would you like to just come and DJ for us?’ And he was like, ‘yeah, sure'," he said on an episode of The Lightweights podcast.
