It's definite, Lee will be on This Morning on Monday singing something from Legally Blonde. Only his name mentioned, nothing about anyone else from the show being there.
I love Lee's facial expressions - especially the one where he's saying "Don't watch me change!" and the one after he says "I look like Warner!"
On viewing the performance for a second time, I noticed that when Elle sings "Take a deep breath...", he does! His subsequent expressions in those first few lines of the song crack me up!
I agree about the chemistry between Lee and Carley.
