Big Sean may have some steep competition with singer Ariana Grande. The petite 20-year-old tackled the G.O.O.D. Music signee's hit 'Guap' while visiting Big Boy’s Neighborhood on Power 106 in L.A. recently.

Grande insists that her entourage sing the hook while she spit Sean's rhymes, including his infamous "Oh, gawd" and "Boy" tagline. She kept it a tad PG-13 by censoring herself for lines like "G.O.O.D. Music in this bitch, now drop that motherf---in' beat!"

The 'Baby I' songstress came in a bit early on a verse but still managed to hold her own throughout the track.

"You sound so cute," Big Boy said of her rap-along.

"No I don't, I sound stupid," she said with a laugh.

Perhaps Grande will showcase some more of her rapping skills on her debut album, arriving Sept. 3.
