Ashton’s mercy dash to be by Demi Moore’s side?

Ashton Kutcher arrived back in Los Angeles last night after his troubled estranged wife Demi Moore was released from hospital today.

The 33-year-old actor looked strained as he quickly jumped behind the wheel of an awaiting SUV and sped off into the night after touching down at LAX airport.

His arrival comes as the 49-year-old actress left the Sherman Oaks hospital where she has been recovering from a health scare which occurred on Monday night.

The actor has been in Brazil for the last week where he has been busy attending a slew of events, including a Brazilian fashion show and a Florence And The Machine concert.

But it appears that he may have cut his trip short following Demi’s health drama.

It is unknown whether he will rush to be by the actress’ side, but his serious demeanor was certainly in stark contrast to Tuesday night, when he was seen partying in Sao Paulo just one night after Demi was first hospitalised.

The Two And A Half Men star looked like he didn’t have a care in the world as he jumped up and down to a performance by Florence and The Machine on Tuesday night.

Ashton was seen with a female companion as he celebrated at the Summer Soul Festival at Anhembi Arena in Brazil.

Demi was rushed into hospital on Monday night at around 11pm after inhaling nitrous oxide, according to reports.

She is understood to have been released from the Sherman Oaks hospital today.

Sao Paulo is six hours ahead of L.A., so news of the Demi’s heath drama broke around the same time that Ashton was enjoying himself.

A spokesperson for the star was not available for comment earlier today.

Earlier today TMZ.com posted a video of Kutcher leaving a nightclub Wednesday night.

While the photographer asked Ashton: ‘Is Demi okay?’ the actor refused to comment and got into a car with two people including a blonde woman.

Demi’s daughter Rumer Willis is said to have tried to contact Ashton since he has been in Brazil about her mother’s health.

A source told Hollywoodlife.com: ‘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.’

Other reports say that Ashton is worried about his estranged wife but is moving on.

‘Ashton is deeply concerned for Demi,’ a source told People magazine.

‘He still cares about her and wants the best for her. But their marriage is ending and they are both moving on with their lives.’

Ashton has not made comment on his estranged wife’s condition on his Twitter page but has been updating fans with other topics, his last post was on early Thursday morning, Brazil time.

It has also been reported that Chloë Sevigny has just been drafted to star in Lovelace, which Demi just dropped out of.
