The Voice‘s zaniest coach Cee Lo Green is given to rocking jumpsuits that look like they’re made of Muppets and stroking his stuffed cat Purrfect. Does that make him crazy? Possibly. But when Green showed up for a guest stint on Nick’s How to Rock (airing tonight at 8 p.m. ET), he was surprisingly understated, donning a plain black T-shirt and relatively few flashes of bling. “I’m used to seeing him in big, colorful feathers and all these crazy outfits,” laughs the show’s 15-year-old star Cymphonique Miller, “and he was really down-to-earth with his outfits when he came on set.”
Green’s no-nonsense air didn’t end with his ensemble, says Miller. “Whenever I work with an artist or someone from the music industry [who comes] into the acting world, it’s always interesting to see if they memorize lines or take the acting seriously,” she notes, adding happily that Green was “really cool and professional…. He really brought his own flavor to the role.” Green also brought his family, a fact Miller appreciated given her own famous pedigree — she’s the daughter of Master P and sister to the artist formerly known as Lil’ Romeo. Below, Miller dishes on what exactly she is doing on stage with Green, another exciting star cameo to come, and the best advice she got from upcoming X Factor judge Demi Lovato.
