And now, Lady Gaga performing “Judas” for the first time ever.

Donning her best Britney at the 1999 VMA’s skin-tight couture (I keed, I keed), Mademoiselle Gagz and her troupe of pious prancers turned out a semi-spastic, mildly epileptic rendition of her latest RedOne-produced smash.

The Lady also sat down and spoke with Ellen prior to her performance to discuss her fans, her fashion, and “feeling like a loser” in her latest HBO special sneak peek. Oh, and her surrealist mole of course!

Watch for the “Judas” music video to premiere during next Thursday’s episode of American Idol.

“Judas” was released on April 15. (iTunes)

BOW DOWN IN THE PRESENCE OF FLAWLESSNESS.

Although her upcoming fifth studio album was recently pushed back to September, Kelly Clarkson appeared on The Ellen DeGeneres Show today to deliver an flawless medley of hits, including “Miss Independent,” “Walk Away” and “Since U Been Gone.”

Honestly, she just nailed it: The voice is perfection. The look is perfection. The performance is perfection. I really can’t even…UTTERLY EFFORTLESS!

Kelly Clarkson is truly one of the greatest vocalists of our generation, and this performance only serves as further proof.

And now, I’ll leave you with the performance that sealed the deal for me as a lifelong fan:

Can’t wait for the new tunes, K. Clarks!

Above is Riri‘s pre-taped performance of “Rude Boy” on The Ellen DeGeneres Show, the latest single off of Rated R and MuuMuse’s unofficial anthem.

Notice that with a live band, “Rude Boy” is arguably EVEN RUDER THAN THE ORIGINAL. Rihanna works the stage like it isn’t even an issue, gyrating against the nasty guitar licks and slamming drum noise like a good girl gone bad rightly should.

Even while rocking a visor, Rihanna still looks fresh to death. AMAZING.

Love this performance, love this song, love my Riri.

Rihanna appeared on The Ellen Degeneres Show today! Watch above for a six minute permi-smile.

Riri also performed a spacy, rockier version of “Don’t Stop the Music” (top) and a solid rendition of “Hard” (bottom). I cannot believe what a performer she’s becoming. Just look at that fearless audience interaction during “Music”…j’adore!

I’m still in love with everything about Jennifer Lopez‘ boxing-themed performance of “Louboutins” on the AMA’s, except this time, she’s gone and done it even better the second time around.

Just look, there’s no tripping after rocketing off the back of her man servant! Plus, not only does she come out wearing that gold warrior piece after the quick-fix changing section in the dark (which is brilliant), but she throws on a literal pair of Louboutins to boot! Double brilliant! And how about her “walk it out” bit with Ellen at the end? Too good.

“Louboutins” may never touch the radio, but it’ll always be a cult favorite ’round these parts.

Viva la Jello!

Because it deserves its own post, Britney Spears and Ellen Degeneres go around town to spread holiday cheer.

Haven’t been around to doing this in the past weeks, so I’m bringing it back! Check out some of the latest clips from SNL, as well as an assortment of miscellanea. Credit to field reporter vice co-vice president Nora for finding the final clip.

Kristin Wiig continuing to prove why she’s going to be the new it girl of SNL.

And again.

Christopher Walken.

Now an internet phenomenon.

Ellen, proving the Hawaii Chair is workable and efficient.

Here is Kylie Minogue‘s brief interview with Ellen on The Ellen DeGeneres Show. Sadly, there’s no humor here. Seeing two idols together is always such an endearing experience, though I don’t think anyone quite expected the interview to pan out as it did just now. Kylie reveals quite candidly some new information regarding her bout with cancer. By the end, Ellen does as well. It’s actually all a bit shocking and unsettling, though as you can see, everyone is doing quite fine now. Right here are two women who truly deserve the title “role model.” Love them.

On a lighter note, her latest performance of “All I See” on Ellen. It’s not as fluid as it was on Craig Ferguson, though the set design is ten times more Kylielicious.
