Bruno Mars May See 'Schweddy Balls II' On 'Saturday Night Live'

Mars will pull double duty as host and musical guest on this weekend's 'SNL,' and, yes, he's sort of freaked out by that fact.

This weekend, Bruno Mars will join an illustrious club that includes the likes of Britney Spears, Taylor Swift and Mick Jagger when he pulls double duty as both musical guest and host on "Saturday Night Live." And though he's honored to join their ranks, he'd be lying if he said he wasn't just a tiny bit nervous about the whole thing.

"It was weird, because I'm not an actor or a comedian, and they asked me to do it. It was surreal," he told MTV News. "It was one of those moments where it's like 'Oh man, that would be so fun ... yeah, let's do it!' and then you hang up and you're like 'Wait a minute ...' But, I'm excited, man! I've got nothing to lose! I'm the 'Grenade' guy forever."

So he's heading into "SNL" free of pressure and ready to rock. Which is why he's got big plans for the show ... including reprising one of the most popular skits of the past 15 years.

"I always think of Alec Baldwin, and the 'Schweddy Balls' skit ... that's one of the all-time best," he laughed. "Alec Baldwin always kills it. I hope he can make a little cameo and help me out ... we'll do 'Schweddy Balls II.' "

And though he might seem confident, Mars will admit that there is one aspect of hosting "SNL" that freaks him out: the opening monologue. Because even though he's performed before thousands live (and millions on TV), the thought of stepping out onto the stage and having to tell jokes ... well, that's something he's definitely never had to do before.

"Yeah, it's different, because you're talking, and it's TV and you just go up there, and you're so naked, and it's a comedy show," he said. "I shouldn't be doing this, should I? This was a mistake. This might be the biggest misstep of my career!"
