The breakout cast member from Nickelodeon’s “Victorious,” Ariana Grande will star in the cabler’s spinoff series, “Sam and Cat,” and is recording an album with Universal Republic — proof that TV and recording execs are noticing what the Internet has long realized: Grande is a bona fide star. With her Jolly Rancher red hair, Grande counts nearly 3 million Twitter followers, and her YouTube videos draw millions of hits. In fact, her casually recorded cover of Adele’s “Rolling in the Deep” garnered more than 32 million views.Untitled Entertainment’s Stephanie Simon discovered Grande in her award-winning performance in the Broadway musical “13,” and the multi-talent insists that singing is still her passion and priority. “I want to win a Grammy one day,” she says. “I don’t want to be a little girly flash in the pan.” In the meantime, Grande is looking forward to a Nick TV movie, film projects and the launch of her Nick series (with “iCarly’s” Jennette McCurdy). Recently, Grande took a meeting in hopes she’d sway producers to hire her for a project, only to learn it was they who were courting her. “I got offered a role I didn’t have to audition for? That blew me away,” she says.
