Last night’s Lip Sync Battle split apart the “Push It” duo, Salt-N-Pepa! Cheryl “Salt” James performed Kelly Clarkson’s pop rock anthem, “Since You Been Gone.” And she was adorable! She really showed us another side. Take it from LL.

LL Cool J: Who knew you were a pop diva?

Then it was Sandra “Pepa” Denton‘s turn to strut on the stage with legs for miles, with Katy Perry’s “Firework.” Nice job!

Thursday nights Lip Sync Battle, kept it all in the family, as Derek Hough battled little sis, Julianne Hough. Both professional dancers, the brother and sister are also on Dancing With The Stars together.

At first I was like, “Well… I know Dancing With The Stars is popular, even though I love So You Think You Can Dance way more… so eh.” But I should have known that professional dancers, used to choreographing spectacular productions with less than professional dancers, would put on a show.

Watch the videos below.

Woohoo! That’s how you do a lip sync show! Thursday night’s Lip Sync Battle pitted Malin Akerman Vs. Stephen Merchant, and the competition was fierce. Akerman brought the severely sexy, and Merchant brought the “I wish I was sexy.” But you know what? He is so funny that it is kinda sexy.

Touted as the veteran of the show, he definitely has the advantage. Executive producer Merchant invented the game along with executive producer John Krasinski and Emily Blunt, first appearing on The Tonight Show Starring Jimmy Fallon, where it took off.

Lip Sync Battle preview videos are here! This week, Malin Akerman (forever Silk Spectre II) silently mouths words against Stephen Merchant, executive producer of the show, and all around hilarious writer of such shows as The Office and Extras. The clips show Malin Akerman performing “Pour Some Sugar On Me” by Def Leppard in a catsuit (Meow!), and Stephen Merchant showcasing his derriere to Christina Aguilera’s “Dirrty” (NOT Meow!). Now don’t let the fact that you may not know who Stephen Merchant is deter you from watching. I too, had no idea, until one fine day on YouTube, looking up lip sync battle clips from Jimmy Fallon shows, and came across a gem of a three-way: Joseph Gordon-Levitt vs. Stephen Merchant vs. Jimmy Fallon. I was hooked immediately.

Watch the two preview clips plus the aforementioned gem below.

It’s my favorite day of the week! Lip Sync Battle day! It’s a talk show titans battle as Hoda Kotb of The Today Show Vs. Michael Strahan of Live with Kelly and Michael, and they both bring it!

Watch the incredible videos below. I can’t wait to see the whole thing tonight!
