Guest mentor Idina Menzel – who voiced the lead character and sang the iconic anthem “Let it Go” in the film — will be on hand to guide the top 10 on the April 29 episode, Variety has learned exclusively.

Menzel will be working with the Idols next week, after America eliminates four contestants on the Monday night’s show (April 23). In this episode, the top 14 contestants will perform solo, with the winners voted through to reveal the new season’s Top 10.

How will the eliminations work? Viewers will be able to vote after this Sunday’s (April 22) episode. The votes will close the following morning, Monday, April 23 at 9:00 a.m. EDT. Viewers can vote online at AmericanIdol.com/vote, via the American Idol app or by text. Fans may vote 10 times per contestant, per method.
