WATCH: Here’s Ariana Grande to Remind Us All That She Has a Beautiful Singing Voice

Let Ariana Grande be known for her gorgeous singing voice, and not her donut licking incident!

The 22-year-old singer gave a surprise performance last night (Dec. 4) in Los Angeles. Grande showed up to Hollywood’s Catalina Bar and Grill, where Vulture writes, “the audience arrived expecting a performance by Jason Robert Brown (and, according to their website, maybe some drinks and Italian-American fare).”

Walking up in an oversized sweater and large-rimmed glasses, Grande looks comfy and casual, looking perfectly chipper as she sang three songs, two of which were composed by Jason Robert Brown from the musical 13 – the musical in which she made her Broadway debut in 2008 when she was only 14-years-old.
