Demi Moore's cougar claws are out again this time on the 30-year-old Will Hannigan who people claim is a dead ringer for his fellow Aussie, Chris Hemsworth.

After being seen with anothe thirtysomething Harry Morton, owner of the Pink Taco restaurant chain, Demi now dates Will Hannigan.

Hannigan, who used to work as a commercial pearl diver, has openly admitted to Star Magazine that he is indeed "close" to the 50-year-old actress.

"We know each other through yoga, and we've become close," Hannigan told the Star. "She's an amazing woman."

According to reports, the pair have been going out for a month and love having massages and sauna before attending their yoga sessions.

'Will is clearly a passionate individual and Demi seems to be enjoying every moment with him," a source of the Star said.

Moore seems to have found romance again but is he good for her? Friends of the actress are a tad worried knowing how hard Moore worked to recover from her drugs overdose episode in January 2012. Moore had a difficult time dealing with her tumultuous split with ex-husband Ashton Kutcher in late 2011.

"I'd hate to see anything jeopardize the positive steps she's made," a friend of the actress disclosed.

Hannigan, who is said to be following the Sikh religion has reportedly messed around with drugs. In an Amazon jungle adventure in Peru, he reportedly dabbled in ayahuasca, "a hallucinogenic liquid brewed from vines that contains the drug DMT." Dimethyltryptamine or DMT is illegal in the United States.

A Youtube video shown below has made the rounds showing Hannigan narrating how he felt during the experience. "I went through some interesting stuff with the mind, and then it got to the point where I was just feeling like I was about to leave my body," he said.

Friends of Moore are concerned that the actress may get involved in his "adventures." A friend told the Star that "There is a bit of concern that Demi might get caught up in sharing all Will's experiences with him."

Meanwhile, friends of the hunky Hannigan describes him as a "loveable drifter."

"He's an interesting character," one pal said. "He's a great guy to listen to - a bit wild but good fun."

"(He's) talented. I remember he has a good voice and can play the guitar," he added.

Hannigan was born in Western Australia and grew up in Victoria. He opened a pearl company, Pinc Pearls, in Bondi where he has been staying in recent years. His company has since stopped operating.

One thing for sure, Demi has a penchant for young and intriguing men.

After breaking up with Kutcher, she also dated the 32 year-old Harry Morton, Lindsay Lohan's ex-boyfriend, as well as Elle Macpherson's 26-year old ex and art dealer Vito Schnabel, and Kiwi actor Martin Henderson.

Kutcher is currently dating Mila Kunis, his co-star in That 70's Show.
