Hollywood's Top 5 Cougar Couples

April 27, 2010 — -- Cougars, pumas, cradle robbers.

Whatever you want to call them, older women are dating younger men – and the theme seems to be getting a higher profile on television and in gossip magazines.

The newest example of a younger man dating a much older woman is Aaron Johnson, 19, a Hollywood newcomer and star of the current box office hit "Kick-Ass," who is engaged to British director and artist Sam Taylor-Wood, 43.

According to People magazine, Taylor-Wood, who is 24 years older than her future husband, already has two children from a previous marriage and is seven months pregnant with Johnson's child. The two lovers met on the set of Taylor-Wood's 2009 directorial debut "Nowhere Boy" and got engaged just months after meeting. An interesting piece of trivia: Johnson is closer to age of both of his step children, Angelica, 13, and Jessie, 3, than his future wife.

Despite what critics may think, Johnson told People that he has found a "wonderful woman."

"She's lovely and she's a fantastic mother," he said. "I am an old soul and she's a young soul."

Meanwhile, Demi Moore, the original cougar, is starring in a new movie "The Joneses," which is now open in limited release. Moore was one of the first women to be widely publicized and praised for dating the much younger Ashton Kutcher.

From all the press about her May-December relationship and other couples like Johnson and Taylor-Woods the amount of cougars on the prowl today has reached a fever pitch.

Even though the answer to why these older women and dating younger men seems fairly obvious, Rachel Sussman, a New York City based relationship expert, said that our culture's obsession to youth is to blame.

"Everyone in our society prizes youth because we believe there is a beauty in youth," Sussman told ABCNews.com. "While there is no saying what attracts whom to what, women today have never looked better. Today everybody works out and women spend time keeping up their appearances."

"I think that there is a lot to be said about being with a seasoned woman who is older than you," Sussman added. "That person has a lot more life experience and can be more interesting than someone who is your own age."

Amelia Parry, the editor in chief of TheFrisky.com, a Web site dedicated to celebrities, gossip, fashion and relationship advice, said that while there is no problem with older women being seen as sexual in nature, they tend to be over sexualized.

"Samantha Jones [of "Sex and The City"] is very much what society thinks of as a sexy older woman and that is gross," Parry told ABCNews.com. "There is a cap that the general society puts on a woman as far as up to what age she can be seen as a sex symbol. The attractiveness and sexuality of older women always seems to surprise and fascinate people.

"It seems that people think when women turn 40 they suddenly aren't interested in having fun, but just because you're 40 and you're a women, you don't have to stop living. Older women today want to be single and having fun and going out and partying."
