Now Demi's got her eye on a guy nine years younger than Ashton!

49 year old Demi Moore, according to Us Weekly, has been on a desperate spiral that includes wild parties, drug use, and young men. An insider says Demi has been really down since splitting with Ashton Kutcher and is surrounding herself with young people to make her feel better.

Demi's favorite youngster to party and flirt with is her daughter Rumer's pal Zac Efron....who is 25 years younger than Demi! She allegedly once tracked down the high School Musical star at a party in L.A. and seemed "out of her mind" at that party.

Demi collapsed and was hospitalized last month after reportedly doing whip-its.
