Christina Aguilera Improves On Rihanna, Beyonce, Gaga and Whitney Houston Material by Aguilera-ising Them on Ellen

What the point of this segment was, I don't know.

Rather than imitate the Divas coming up on the screen, which would have been fun to watch, Christina Aguilera sang the songs as Christina Aguilera. Maybe that was the point! To have Ellen guess the artist, in any way, bar Chrisy naming them outright.  Clearly I've never seen (or heard of) this "Head up!" segment before, but it reads as charades for two people. Am I right? #Confused.

Anywho, my reading too much into this tiny VT my thoughts on the video:

• Christina's contour is awful.
• Christina still has beef with Gaga despite their apparent make up with the  Do What U Want duet on The Voice.  
• And the biggest shock: Christina doesn't know any Streisand!! BURN HEERRRRR!

Seriously, f**k this! Give us new music, already! I'm dying over here, Xtina! .
