What we'll be asking them is up to you, so send us your questions via the comments area below, or on Twitter using the hashtag #AskTheSingers. The duo are a couple off stage as well as on, having met when studying at the Academy of Vocal Arts. You may want to ask them what it's like performing on stage with your real-life partner, how they manage their successful individual careers or anything else you'd like to know.
We'll ask Ailyn and Stephen a selection of your questions via our feed from 2pm on the day, so make sure you follow @TheRoyalOpera on Twitter before then. Recent Q&As include ‘twinterviews’ with singers Joyce DiDonato, Ermonela Jaho and John Tomlinson as well as The Royal Ballet’s Lauren Cuthbertson, Marianela Nuñez and Thiago Soares and Yuhui Choe.
