Rumer Willis was snapped arriving at LAX today to catch a flight out of town, and we're not sure if she's going to visit mom Demi Moore in rehab or if she's taking a break from her, but it certainly seems like the starlet could use a few days of quiet time. Demi's current location has yet to be confirmed, but various media outlets have her everywhere from a treatment center in Utah to her own home in Los Angeles...

Following her mom's hospitalization late last month for smoking a mysterious substance and going into convulsions, Rumer has been spotted out and about numerous times, but she's remained mum on the incident. After hearing the 911 call, it's quite obvious that Rue was with Demi at the time, so we'd have to agree with her pal Zac Efron -- she's handling things very well!

Zac Efron is currently promoting Dr. Seuss’ The Lorax, (he voices the character of Ted), and when he sat down with Access Hollywood Live to discuss the upcoming film, he also dished on his pal, Rumer Willis.

After Rumer's mother Demi Moore was rushed to the hospital for smoking a mysterious substance and going into convulsions, Zac revealed that he has spoken to the 23-year-old starlet and she's handling the situation as best as she can.

“She’s doing OK, she’s doing fine," he told Access. "It’s tough what she’s going through right now, but she seems to be handling it really well." It was previously reported that the two were dating, but those rumors were recently shot down when we spotted Zac going on a dinner date with Lily Collins!

Today Rumer Willis was photographed stopping by CVS in Hollywood, and Demi Moore's oldest daughter didn't flip out like her little sister Tallulah did last week, but she wasn't exactly in a cheerful mood either.

Even though Demi is reportedly seeking treatment at Cirque Lodge in Utah, it looks like her family is trying to focus on the positive things in their lives and not dwell on her shocking meltdown. Last Friday Bruce Willis threw a bash to celebrate Tallulah's 18th birthday, and we've spotted Bruce (along with pregnant wife Emma Hemming) and Rumer out and about several times since Demi was hospitalized.

Tallulah Willis turned 18 yesterday, and Bruce Willis and Demi Moore's youngest daughter celebrated her birthday at her father's new Beverly Hills mansion last night. We snapped Rumer arriving around 8pm, but there was no sign of Demi (or ex-hubby Ashton Kutcher).

A photographer tells X17online exclusively, "A bunch of Tallulah's friends came, along with her sisters and her dad Bruce, but we were waiting and waiting to see if Demi would show up — like hiding in the back of a car or something — and she never did."

Guests at Tallulah's b-day bash enjoyed catering from an organic food company, and while the music got pretty loud, things died down by 11pm. Sounds pretty standard for an 18-year-old's bash, right?

It appears Demi Moore's recent breakdown has taken quite a toll on her daughter, Rumer Willis.

The 23-year-old looked painfully thin as she made her way to Sephora to indulge in some major retail therapy, before heading to her actual therapy session in LA, on Thursday afternoon.

Willis, who donned a vintage blue tee with the phrase "Beauty Is Within," has reportedly been spending more time with dad Bruce, his pregnant wife Emma Hemming, and her 17-year-old sister Tallulah at the actor's West LA condo, while Demi receives the help she needs.

Moore has not been seen in public since she was admitted to the hospital for "stress" and "exhaustion" last week, but she's currently seeking "spiritual counseling," according to E! News.

Since leaving the hospital, both Bruce Willis and Ashton Kutcher have dropped by to check up on Demi.

A somber-looking Rumer Willis went to the Beverly Glen mall in Brentwood on Monday, and later we spotted the Sorority Row starlet grabbing some dog food at a pet store in Los Angeles. But what caught our eye was her handgun handbag! Talk about packing heat.

When asked about Demi Moore's hospitalization, Rumer refused to comment, and it appears as though her mother's troubles have affected her as well -- it seems like she's lost a few pounds, and she definitely doesn't look like she's been sleeping well.

As you know, Demi was rushed to the hospital last weekend after smoking a mysterious substance and going into convulsions, so we're glad to see that Rumer is able to handle her business. Hopefully her mother is getting the rest and help she needs...

Demi Moore's oldest daughter Rumer Willis appeared distraught as made her way to visit her mom on Wednesday.

After Moore was admitted to the hospital for "substance abuse" issues, the 23-year-old was the first family member spotted at the hospital, frequently ducking outside for a smoke break, and looking visibly shaken as she chatted on her cellphone.

Sources close to Willis say she's been worried about her famous mom for weeks and was even concerned enough to reach out to estranged husband Ashton Kutcher, who is currently in Brazil for fashion week and a catalog shoot.

"Rumer is devastated. She worries day and night about her mother and has been watching her mom fall apart. Rumer actually reached out to Ashton on several occasions and he just blew her off. He either wouldn’t answer or he’d say he’d help but nothing would happen," a source tells HollywoodLife.com.

On Jan. 11, Moore was seen partying it up at The Roosevelt Hotel in Hollywood with Rumer, and hitting on a much younger man, 27-year-old 90210 star Ryan Rottman.

"[Moore] found ways to touch him all night, and at one point when he was in front of her, she was grinding on his butt," the source told People, "His shirt came unbuttoned, and she started tickling his bare chest playfully. She seemed really happy to be out with her daughter's friends." Rumer was reportedly infuriated and embarrassed at the scene.

Reports have claimed Demi was hospitalized for anorexia, exhaustion, stress, a seizure and even an overdose of nitrous oxide.

We had to do a double take as Scout Willis exited a car, looking just like Lady Gaga, while in Paris, France, on Friday.

The stylish daughter of Bruce Willis and Demi Moore is in "The City of Light" with her dad and sisters, where she'll see little sis Tallulah make her "debut" at the Bal des Debutantes, held on Saturday evening at the Hotel de Crillon.

Meanwhile mom Demi, who has recently filed for divorce from Ashton Kutcher due to cheating allegations, opted to spend Thanksgiving at home in LA this year.

C'est la vie!
