Listen to Miley Cyrus Radio on iHeartRadio

Miley Cyrus is set to sing some parting words to Chelsea Handler as the curtain falls on Chelsea's late-night talk show.  The pop star has signed on to perform on the series finale of "Chelsea Lately" next week.  She won't be treating viewers to her well-known onstage antics, however. 

It looks like Miley will be channeling Bette Midler's 1992 "Tonight Show" farewell song to Johnny Carson, as she'll be covering the Roy Orbison song "It's Over." 

The star is currently on a break from her "Bangerz" tour, and will return to her twerking routine when it picks back up in South America next month.  

The series finale of "Chelsea Lately" airs on Tuesday, August 26th at 11 p.m. Eastern on E!.  It spent seven years on the air.
