We already knew she buzzed all her hair off for her role in the upcoming and fourth Mad Max film, but Charlize Theron hadn't given us a good look at it until now!

Tom Hardy, Nicholas Hoult and Rosie Huntington-Whiteley will star in Mad Max: Fury Road, and according to writer/director George Miller, “Mad Max (Hardy) is caught up with a group of people fleeing across the Wasteland in a War Rig driven by the Imperator Furiosa (Theron). This movie is an account of the Road War which follows. It is based on the Word Burgers of the History Men and eyewitness accounts of those who survived.”

Can't wait for our first look at this flick!

Not only are Kim Kardashian's leggings a bit on the sheer side, but is she even wearing underwear? Or did her butt cheeks swallow up a thong in the time it took her to walk from her car to the gym?

When the 32-year-old reality starlet isn't busting her booty at the gym, she's constantly keeping us updated via Twitter and Instagram, but after recent changes with the privacy of the latter social networking site, Kim might be deleting her account!

"I really loved Instagram :-( I need to review this new policy," Kim tweeted the other day. "I don't think its fair." Kim is Instagram's top user with approximately 5,726,343 followers, so maybe they will re-think their policy! (Earlier in the week, Instagram announced that the addendum would allow them to sell user photos to third parties without getting permission or compensating the user, but Instagram co-founder Kevin Systrom later apologized for the "confusing" language and said that the company has no intentions of selling photos.

What else has Kimmy been doing? Cosmo E-I-C Joanna Coles tweeted, "Guess what @KimKardashian and I did yesterday... cc: @Cosmopolitan" and posted this photo from their cover shoot:

Katie Holmes arrived for her Late Show appearance in New York looking absolutely perfect in pink.

The sexy actress will definitely get Dave Letterman's attention in this sexy, form-fitting number!

Suri's 33-year-old mom has been busy promoting her latest project Dead Accounts on Broadway.

Although Katie usually dresses down while cruising around the Big Apple, we have to admit ... she cleans up well! That said, we're not so sure about the number she wore after the show:

We'll never miss an opportunity to post a photo of the hotness that is Zac Efron!

The 25-year-old actor was spotted on the set of Are We Officially Dating?, which is about "three Manhattan bachelors make a pact to have as much fun as possible while remaining single," according to IMDb. The film also stars Imogen Poots as Zac's love interest, but we're more interested in who Zac is dating IRL! He was last linked to Lily Collins, but the duo split earlier this year, and as far as we know, he's still single!

When Zac appeared on The Ellen DeGeneres Show in October, he lamented, "Dating is kind of hard. A forced awkward situation is very strange. Especially for me, for some reason. I like to go and do something adventurous. I like to go out and do some sort of crazy activity."

He added, "You always have to be careful, I guess, about that kind of thing. Every day is a new experience and I take it as it comes. Some people I worry about, some I really don't have to."

She's certainly got her hands full!

Jennifer Garner was spotted with her daughters Violet and Seraphina and baby Samuel after school on Wednesday, and we're not sure where hubby Ben Affleck was, but Jen didn't seem to have a problem juggling activities and pick ups with all three of their children!

Jen recently returned home from New Orleans after shooting The Dallas Buyers Club, and while Ben will be busy with back to back projects (Focus and his Whitey Bulger biopic, not to mention awards season and promoting To The Wonder, which comes out next April ... whew!), she doesn't have any other movie gigs lined up for next year. We know Ben doesn't want to be a stay at home parent, but she certainly doesn't seem to mind!

Hard to believe Courteney Cox is 48!

The Friends star looked fresh and fabulous while doing a little holiday shopping at Maxfield's in Beverly Hills.

We love that Ms. Cox paired a simple grey sweater, dark skinny jeans and black boots to hit the shops.

Casually cute!

Ke$ha is hoping to clear the air regarding the lyrics to her hit song "Die Young."

The 25-year-old singer received criticism following the school shooting at Sandy Hook Elementary School in Newtown, Connecticut.

The songstress released the following statement:

“After such a tragic event I was feeling a lot of emotion and sadness when I said I was forced to sing some of the lyrics to Die Young.

Forced is not the right word. I did have some concerns about the phrase “die young” in the chorus when we were writing the lyrics especially because so many of my fans are young and that’s one reason why I wrote so many versions of this song. But the point of the song is the importance of living every day to the fullest and staying young at heart, and these are things I truly believe."

This statement is very different from the singer's Tweet earlier this week. Ke$ha had written, "i understand. I had my very own issue with ‘die young’ for this reason. I did NOT want to sing those lyrics and I was FORCED TO.”

The controversial Tweet has since been deleted.

Ahh, young love! And there's nothing like the smell of smoke from your beau's cigarette blowing in your face...er, well...

Shenae Grimes, 23, and her fiance Josh Beech, 24, were spotted in Hollywood yesterday, and even though the duo have nailed the dirty hot hipster look, they are pretty cute together!

Grimes confirmed their engagement on her website earlier this month, writing, "Thanks for all the congratulations everyone, I’m a very happy lady indeed and all the warm wishes are well appreciated! We plan to keep our special day very private and we hope everyone can respect that. Thanks for the love, right back atcha!"

Grimes and Beech started dating in the spring of 2012 ... wonder when they plan on walking down the aisle?
