Whether she's dressed up for a meeting, or dressed down for the gym, Ashley Greene manages to look absolutely gorgeous at every angle!

The Twilight star showed off her slender frame in a red sweater, dark skinny jeans and high heels while on her way to a meeting in Beverly Hills, but later changed into casual gym clothes for a workout in Studio City, on Thursday afternoon.

Much like her charter in Pan Am, Greene's upcoming film, Butter, features a very steamy girl-on-girl make out sesh ... with Olivia Wilde!

Ash told Lucky mag of the kiss, "It wasn't that awkward. It's the same idea as having to kiss a male co-star and it's not real. Olivia is such a cool chick and very professional. So we were just messing around and cracking up in between scenes ... And now I'm the envy of every straight male everywhere!"

Looks like these lovely ladies may have a secret admirer!

Vanessa Hudgens and Ashley Tisdale were snapped leaving the dance studio in Hollywood today, and the ladies both carried beautiful floral arrangements back to their cars. Ash tweeted, "Dance class with @slaughteration and Nessa #whoruntheworld" and she even posted a video of them shaking it to Beyonce's hit single. Check it out below!

Tyler Shields

We already knew Demi Lovato was doing an edgy shoot with celeb shutterbug Tyler Shields, and the pics have finally been released! It's kinda amazing how a single piece of candy can spice things up...

Demi tweeted, "Check out my new twitter picture taken by the brilliant @tylershields!!" and Tyler wrote on his blog, "I have received more emails asking me to release this shoot then any other shoot I have ever done Lovatics are dedicated fans! Demi killed it the glass smashing shot we did in 1 perfect take!" Well, she is a Disney star after all -- we'd expect nothing less!

Check out the rest of the shots in the gallery below!

Demi Moore has beefed up security at her Beverly Hills home, X17online can report exclusively.

Sources tell X17online that the 49-year-old actress has hired an armed bodyguard to approve of the people entering her residence, and he's been spotted standing at the end of her driveway with a clipboard of names.

It's uncertain whether Demi is seeking treatment outside of her home, but ex-husbands Ashton Kutcher and Bruce Willis were both spotted visiting her $3.1 million pad yesterday, so it appears as though she is spending time there with those closest to her.

Demi was rushed to the hospital last week after smoking a mysterious substance and going into convulsions, and her oldest daughter Rumer was with her at the time of the incident. Bruce and Demi's youngest daughter, Scout, who turns 18 tomorrow, reportedly lives with the Die Hard actor, so it seems as though everyone will be taking turns visiting Demi as she recuperates.

We're in love with Ben Affleck's gorgeous German Shepherd, but we're glad we're not responsible for picking up after the pup!

The Oscar winner was spotted taking his canine companion for a walk in Los Angeles this morning, and he made sure to scoop up every last bit of ... well, you know. There's definitely a lot of it, so we wouldn't want to get on his bad side!

Madonna is nervous about performing the halftime show at Sunday's Super Bowl XLVI, and she's not hiding it!

At an NFL press conference Thursday, the 53-year-old performer admitted to the crowd:

"In the over 25 years of performing that I've done, I've never worked so hard or been so scrupulous or freaked out as I have been maintaining my sanity and making the most amazing show for the Super Bowl."

If you're hoping Madonna's will have a "Janet Jackson" halftime moment, don't hold your breath. Madge adds:

"Great attention to detail has been paid to my wardrobe. There will be no wardrobe malfunctions. Promise."

The pop icon says she's been working on overcoming a recent hamstring injury with a "lot of warmups, taping and ultrasound."

Madonna revealed that she's dedicating her performance to her father.

Russell Brand was spotted arriving at his yoga class in Hollywood this morning clutching a can of coconut juice, and the British comedian got to the studio before 9am. Talk about an early riser!

After announcing that he was splitting from wife Katy Perry in late December, Russell maintained a low profile, and it was only two weeks ago that he started stepping out in public again. While he hasn't commented to photographers or news outlets about his failed marriage, it does seem like the possibility of a tell-all book is still quite likely!

Attention Modern Family producers ... Britney Spears wants to be on your show!

The 30-year-old pop star responded to a fan who told Brit she should "find a way" to be on the hit ABC show. Britney Tweeted, "Ahhhh I would love to be on it!" Just days ago, the mama of two wrote, “I know everybody is excited about the Super Bowl, but I personally can’t wait to see the next episode of Modern Family! Funniest show on TV.”

And it seems like there's a very good possibility that this could happen, as a source close to the starlet tells X17online exclusively, "ABC is just as excited about the idea as Britney's fans." Hopefully there will be an announcement about this soon -- we've love to see the pop princess back on the small screen!

This wouldn't be Brit's first cameo on a primetime hit show. Back in 2008, the singer appeared on an episode of How I Met Your Mother.
