So excited that Nick and my gorgeous friend Jamie Reid have asked me to sing for their new musical soundtrack of The Little Prince- playing the part of The Little Prince himself. I can’t say much more but I will tell you the other leads are Hollywood Royalty and I’m SO excited. Hint: #thegreatestshowman #lesmiserablesHmm. My guess (without having looked up everyone else in both casts), is Hugh Jackman.
