Miley Cyrus [1] stopped by The Tonight Show Starring Jimmy Fallon on Thursday and ended up having an extremely honest interview . . . well, sort of. The singer, who's in town to host Saturday Night Live [2]'s season 41 premiere on Oct. 3, tested her quick acting skills by taking part in an "emotional" interview with Jimmy. The pair carried on a regular conversation but had to act out certain emotions when a bell rang. In addition to being superdefensive, Miley was also fake polite and kept trying to one-up the host. But the funniest moment of all came when Jimmy snuck in hilarious statements about Miley's over-the-top outfit. "Your ring is so subtle," he joked, referencing Miley's huge heart-shaped ring. "I didn't even know you were wearing one." Watch the funny clip above, and then check out this Good Burger reunion that Jimmy made happen last week [3].
