MICHAEL DOUGLAS ADMITS TO TAKING VIAGRA & CIALIS! HEY! IT'S HARD WHEN YOU GOTTA KEEP UP WITH A YOUNG & BEAUTIFUL WIFE!

Michael Douglas literally has a prescription for a hot marriage.
In an interview in the March/April issue of AARP magazine, Douglas, 65, admitted he uses modern medicine to satisfy wife Catherine Zeta-Jones, who's 25 years his junior.

"God bless her that she likes older guys," he said.

"And some wonderful enhancements have happened in the last few years — Viagra, Cialis — that can make us all feel younger."

The two-Oscar couple — he won for "Wall Street" and she won for "Chicago" — tied the knot in 2000.

They have two kids -- daughter Carys, 6, and son Dylan, 9.

Douglas, who's been filming the "Wall Street" sequel in downtown Manhattan, has been relatively low-key since their marriage when it comes to work.

He's taken a backseat to his wife's career.

Zeta-Jones is currently starring on Broadway in the revival of "A Little Night Music."

"I'm not so concerned about my career," Douglas told the magazine. Instead, he's staying focused on his family.

Douglas said he fell down on the job as a dad to his son Cameron, from his earlier marriage to Diandra Luker. Cameron is in a federal prison, following an arrest for involvement in dealing crystal meth.

"I think it's easier for me to be a good father" these days, Douglas added. "I see the confidence my kids have got versus the struggle for confidence that I had or that Cameron might have dealt with."
