Idina Menzel was among the honorees at the 2014 Billboard Women in Music Awards, handed out yesterday, Dec. 12 in New York City. The IF/THEN star was honored with the Breakthrough Artist of the Year award, a brand new honor added to the ceremony now in its ninth year - in addition, Menzel honored by members of A BroaderWay Choir, who sang a "Defying Gravity/Let it Go," mashup. Check out their performance below!

"I wasn't prepared for that!," an emotional Menzel commented following the performance. "If you ever need to be reminded of taking risk, just spend a little time with these wonderful women who come out of this city into the country and escape from their everyday life. They're my inspiration. Thank you."

Menzel has performed internationally, both in musicals (she brought Elphaba to London's West End) and as herself in a concert tour. Other film and television credits include Enchanted, Ask the Dust, Glee, and Rent. Solo albums includeBarefoot At The Symphony (a live recording of her PBS special by the same name), I Stand, Here, and Still I Can't Be Still.

If/Then is now playing at the Richard Rodgers Theatre on Broadway, with Tony winner Idina Menzel leading the cast, which also features Anthony Rapp, LaChanze, James Snyder, Jerry Dixon, Jenn Colella, Jason Tam, Tamika Lawrence, and Jackie Burns.

If/Then follows Elizabeth as she rebuilds her life in New York, a city of infinite possibilities. This contemporary musical is set where choice and chance collide. In one moment, Elizabeth will lead parallel lives. This is the story of both.

If/Then is an original Broadway musical which reunites Tom Kitt (music), Brian Yorkey (book and lyrics), and Michael Greif (director), the creative team behind the Pulitzer Prize and Tony Award-winning musical, Next to Normal. If/Then is being produced by David Stone, who produced both Wicked and Next to Normal.
