We weren't expecting Ashton Kutcher to comment on Demi Moore's hospitalization, but we also weren't expecting him to be moving on so quickly!

The 33-year-old actor is currently in Sao Paulo, Brazil, and based on these Twitpics, it seems like he hasn't got a care in the world. In addition to posting these shots online ("Roughing it" and "Surfing the streets of Sao Paulo," he wrote), he sat front row at the Colcci fashion show on Sunday night, and he was snapped leaving a Sao Paulo nightclub on Tuesday with a hot mystery blonde. When photographers asked him how Demi was doing, he had no comment, and he still hasn't released any sort of a statement about his ex-wife.

After the couple announced their split in November 2011, Demi has appeared stressed and noticeably thinner when we've seen her out and about, so it really came as no surprise when it was confirmed that she was hospitalized for "exhaustion" over the weekend. Of course, we'd expect Ashton to say something at this point, right? Or are they not on speaking terms?

Lindsay Lohan is reportedly going to be sued by a nanny who claims the actress injured her after a hit and run in September 2010.

Witnesses told TMZ that Lohan allegedly ran a red light in her Maserati in West Hollywood, and she struck Nubia Del Carmen Preza, who was pushing a stroller through an intersection.

Though the child wasn't injured, Preza claims she was, and a source on the scene added that "3 of the 4 wheels on the stroller became airborne" during the accident.

Despite this report, Lohan's rep tells X17online, "Neither Lindsay nor her attorneys have been served with this lawsuit."

Rihanna and her controversial knuckle tattoos left Giorgio Baldi Tuesday night, and the 23-year-old songstress soaked up all the attention.

The "We Found Love" singer, wearing a form-fitting tank and white $800 Christian Louboutin heels, inked her knuckles with the words Thug Life ... in honor of 2pac. Love how she's thuggin' it while wearing uber-pricey shoes. So hardcore.

RiRi recently Tweeted:

"All these b*tches screaming that 2pac back #THUGLIFE."

2pac, who was shot to death in Las Vegas back in 1996, had the same two words tattooed on his stomach.

So far, Rihanna has 15 tattoos! We have a feeling she's not stopping anytime soon.

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.

After nearly twenty years of sobriety, it appears Demi Moore has fallen back into a dangerous lifestyle.

Within the last year, the Ghost star's friends have become increasingly worried about her, and soon-to-be ex-hubby Ashton Kutcher had reportedly grown incredibly annoyed over her wild behavior.

"Really, it was over the last year her friends saw a change," a source recently told People. "She wasn't sleeping as well, didn't seem to be eating and looked really gaunt."

Sources close to the ex-pair also tell People that Moore's prescription drug use was a huge turn-off to the Two and a Half Men star. "It was a sticking point for Ashton. He wanted her to take care of herself and get a hold of things, and she wouldn't," said the source.

In August 2010, at a Snoop Dogg concert in Las Vegas, Moore decided to climb on stage and dirty dance with the rapper, while Ashton looked on in embarrassment.

The St. Elmo's Fire star was admitted to the hospital on Monday night, after a friend called 911 at 10:49 p.m. when she began to suffer a seizer. The star was doing "Whip-its", gaseous canisters of nitrous oxide often inhaled from whipped cream dispensers, when she suffered the attack, according to TMZ.

Moore’s publicist declined to comment on the reports of substance abuse, but did say she is seeking treatment for "stress and exhaustion.”
