Jenny is officially back on the block!

Last night, Jennifer Lopez released “On The Floor (feat. Pitbull),” the lead single from her upcoming studio album, LOVE?, to iTunes. Since then, the song has climbed to the #1 spot in France, Sweden and Finland, as well as hitting Top 10 in several countries around the world.

Coupled with her digital sales success, Billboard has just confirmed that the song will debut at #40 on the Pop Songs chart, marking her first appearance on the chart since 2007′s “Do It Well” (which peaked at #29). Huzzah!

The “On The Floor” video will premiere on March 3 on VEVO, but we’ve already gotten a special behind-the-scenes sneak peek courtesy of Access Hollywood. Hang tight until the :45 mark to see J-Lo busting some serious moves–she’s still got it!

“On The Floor” arrives nearly one month prior to the release of LOVE?, Lopez’s long delayed seventh studio album due for release on March 29. The record is being produced by Lady Gaga hit-maker RedOne and the legendary chairman and CEO of Island Def Jam, LA Reid.

RedOne recently spoke to Entertainment Weekly last week regarding J-Lo’s upcoming record:

The sound, as you might guess, nods to Lopez’s roots — but it’s more than that. “A little bit of the Latin flavor is infused in it,” RedOne explains, “but I would describe it more as a global sound. It is all about love and covers all emotional sides of Jennifer. She is in a good place.

To top it all off, today happens to be the birthday of her baby twins! Awwww.

Congratulations all around, J-Lo!

FLAWLESS.

There are times when a photo appreciation post proves necessary. This is one of those times.

Here we have Jennifer Lopez posing for Roberto Cavalli, the photo book commemorating the 40th anniversary of the legendary Italian fashion house.

The photo was taken by Mert Alas and Marcus Piggot, the same photography duo responsible for J-Lo’s stunning Spring 2011 Gucci campaign featuring her babies, Max and Emme.

I absolutely adore this photograph. Simply stunning!

Roberto Cavalli was released on January 25. (Amazon)

MuuMuse Approved Tracks for the Week of January 23, 2011

5. Koda Kumi – POP DIVA
J-Pop temptress Koda Kumi’s gone bolder than ever on her 49th single! “POP DIVA” is a brag-filled outburst of pounding beats and wild screeches that rides atop a stinging bass-line similar to the Far East Movement’s “Like A G6.” It’s noisy, it’s erratic–but ultimately, it’s utterly Kumi. (LISTEN)

4. Adam Tyler – I Won’t Let You Go
Up-and-coming L.A. musician Adam Tyler returns with his second single–a gorgeous, heartbreaking electro-pop scorcher that builds and builds with intensity as the song progresses. One to watch in 2011! (LISTEN)

3. Jennifer Lopez – On The Floor (feat. Pitbull)
Kicking off her latest stint as a judge on American Idol’s tenth season, J-Lo premiered the first single from her upcoming album, LOVE?, to radio this week. The spicy songstress enlisted Gaga hit-maker RedOne to produce this floor filler, which capitalizes on all the popular club sounds of late, including the European pulsations of Yolanda Be Cool’s “We No Speako Americano” and Edward Maya’s “Stereo Love.” It’s no “Waiting For Tonight,” but it’s still a proper call to arms. Take it on the floor! (LISTEN)

2. Mya – Fabulous Life
The time is now! Mya seizes the day in this glittery, gleeful electro-pop confection co-produced by J-Pop mastermind Jeff Miyahara and Swedish sensation, Fredro. While this pop treat may only be released in Japan, “Fabulous Life” packs more than enough sparkle and shines to provide universal appeal. (LISTEN)

1. Neon Hitch – Get Over U
You haven’t even debuted yet, and you’re already making me cry at the discotheque? Of all the bad girls, you’re badder than most, Neon Hitch. With sad, stomping synthesizers ourtesy of Benny Blanco and a sorrowful vocal melody contributed by co-writer Sia, “Get Over U” plays like a 2011 continuation of Robyn’s “Dancing On My Own,” proving that the upcoming debut by this whimsical pop gypsy is definitely worth waiting for. (LISTEN)

5. Jennifer Lopez – Good Hit
“I got that good hit…don’t you wish I was your boo?” the industry’s reigning triple threat taunts us on her latest offering, an Auto-Tune overdose of bossiness and bragging that perfectly toes the line between brilliance and garbage. If the video preview that leaked this weekend is any indication, Jenny’s coming back with power power!

4. Keisha Buchanan – Under Control
Above a bouncy electro beat, the former Buchanan busts out a funky fresh, Robyn-like electro-pop cut recently leaked from the recording sessions for her upcoming solo album. Just in case you were fretting about the future of the unceremoniously dismissed Sugababes member, don’t worry–she’s got it under control.

3. Aggro Santos – Like U Like (feat. Kimberley Walsh)
While Cheryl’s busy trying to hold water in her hands and Nadine’s busy trying to pull together the pieces of her flopped solo campaign (Damn you, Tesco!), Kimba’s busy dancing on her own in the club with the UK’s best Pitbull impersonator. It’s a meaningless bar mitzvah banger, but it’s still super fun. And hey–there’s counting…in Portuguese!

2. Nicole Scherzinger – Don’t Hold Your Breath
The former Pussycat Dolls lead finally ticks all the right boxes on her upcoming second solo single: Gorgeous, melodic and instantly memorable, this may just be Scherzy’s breakout moment as a solo artist in her own right. (For real this time!)

1. Britney Spears – Hold It Against Me
Um, duh. Check the review if you haven’t already.

STOP WHATEVER YOU’RE DOING: HAIR FLIPS AWAIT.

Oh my God, I am lit-rally dying right now: A brand new teaser trailer has just surfaced for “Good Hit,” one of the songs from Jennifer Lopez‘s hotly anticipated new album, LOVE?, and it is beyond required viewing.

Decked out in leopard leggings and surrounded by a half dozen hair dryer-wielding hotties, Mizz Jenny from the Block whips her hurr as headmistress of the most glamorous charm school around.

With classes like “Advanced Fierceology” and “Work It Out 101,” who needs that fancy liberal arts education? Sign me up NOW!

And now, some random amazing things that come to mind that I cannot properly articulate in full sentences:

+ Leopard leggings, leopard leotards, leopard lenses. GAGGING.
+ SO. MUCH. HAIR WHIPPING!!! Gorgeous hair, too.
+ Jennifer Lopez looks S-T-U-N-N-I-N-G (In related news: The sky remains blue.)
+ Slick, sick choreography all around. Hot, hot fire!
+ So bright, so colorful–like a J-Pop music video!
+ “I got that good hit. Don’t you wish I was your boo?” = Amazing line.

UTTERLY OBSESSED.

I seriously love everything Jennifer Lopez has ever done, and this is NO exception. She is THE definition of pop.

I need LOVE? in my life–stat!
