^ I think this is the heartplace outfit you were thinking of...I would've DIED if she wore this, as it is one of my favorite stage outfits she's ever worn.

And I hope she doesn't explain or apologize for her look. Her face was a bit puffy as per usual (I think she gets filler before TV lives, and doesn't let them settle in properly before filming) - but nothing about her look was bad or needing explanation.
