I have never seen LB when LBB hasn't cried throughout the show (and I've seen it numerous times). I've heard she even did that in the workshops. It's actually really annoying and distracting (IMO) and takes away from the scene.
During "Legally Blonde" she cries so hard she can barely sing. While I agree it's supposed to be emotional, I think the way Becky Gulsvig plays it, where she's very emotional but appears to be holding back tears, is a lot more powerful and touching.
