It is no secret that Will and Jada Pinkett-Smith have an open relationship. That does not mean that they do not have a spicy relationship of their own. Actually, if they did not have such honest and open communication about their relationship, one of them would be cheating and the other would be heartbroken.

Considering that men like sex in public, Jada happily provides that to her hubby. She tells Redbook, "Be sneaky... your girlfriend's house at a party. The bathroom. A bedroom."

To get the boredom out of their marriage by just being intimate in bed alone, she says, "Think of places outside that are comfortable to have sex. Does he have access to his office? Have a fantasy date. Be his secretary! Pull over on the side of the road... Just switch it up."

I have suggested previously that couples try roleplaying in the bedroom to spice up their relationships. Yep, dressing up is not just for Halloween or for parties. A couple can do it as a fun way of foreplay and just to make things different each time you make love.

That is what Fergie does in the bedroom for Josh Duhamel. She tells Allure magazine, "Oh, girl, I've got a big chest of fun little numbers, ones that I would never wear in public." That's right. She is referring to her large breasts and a lingerie chest full of shelf bras and babydolls.

Unlike other couples who see a big drop in their libido after honeymoon period is over, she says that "Nothing's changed in that department. I like to have fun with my costume onstage; why wouldn't I in the bedroom?"

I know that relationships in Hollywoood are not permanent but that of Lisa Rinna and Harry Hamlin has survived longer than I expected. She recently told MomLogic the secret to keeping their marriage hot.

"You gotta be willing and you gotta be game. You've got to be able to continue [your sex life] when you are married with kids. You may say, "I'm tired and I've been with the kids all day," but you've got to get creative. You have to figure out how to keep your man happy. We try to go away every couple of months -- get a hotel. Sex is the first thing that goes. I try to make him happy. I don't always want to and other times I really want to. It's fun if you allow yourself to let go."

Now I know that Pete Wentz is a metrosexual with all his talk about manscaping and all and that is why he picked sexy woman Ashlee Simpson.

I am now learning more about his relationship with his wife from what he disclosed in an interview with Howard Stern. Now remember that he is a rocker and groupies chase him all the time but he says that when they made love for the first time at the Soho Grand Hotel (which has suites with giant mirrors on the walls).

He provided the juicy details, "Oh my God, you are [sleeping with] the girl of your dreams, and you can watch yourself!" He calls it the "the single best sexual encounter I have ever had."

And to keep the passion alive in their relationship, Ashlee "loves giving me (mean) lap dances," Pete says. Ashlee also wears thongs and "sexy clothes," he added.

I am still wondering why Kid Rock and Pamela Anderson got married in the first place. Both may be a little crazy but maybe they just wanted four weddings and a honeymoon; and some publicity. The Rock-Anderson divorce came soon enough. But the marriage bug had bitten Pam Anderson. After getting a marriage license, Rick Salomon and Pam Anderson tied the knot in Las Vegas.

On the contrary, Kid Rock is bitter about his wedding to Anderson and the fact that she may have lied about a miscarriage. The lesson here is that some men are so afraid of commitment and the responsibilities that come with a marriage that you should leave them alone - don't force the marriage thing on them.

Since Tori Spelling and Dean McDermott got together (they got married in Fiji with just the two of them - how bizarre and how romantic?), they may not have gotten the millions from her deceased father, but they have done well as a couple. They have a successful television show "Tori and Dean: Inn Love" and are parents to Liam. And as Marc Anthony and Jennifer Lopez claim, they too have found working together to be fun. And while many couples need space, this couple want to be together 24X7. So far so good but I would still suggest that you take your breaks from your partner. A little separation actually enhances the relationship.

When it comes to love, Elizabeth Hurley has not been a very lucky woman. Imagine being dumped by a man while you are pregnant? Ouch! And then even Hugh Grant was not too kind to her.

Now her marriage to an Indian man may mean that she might have better chance though Indian men are not known to treat women very well.

It is good to be Elizabeth Hurley; you can invite Elton John to your wedding and he will sing for you. Like Pamela Anderson and Kid Rock who had multiple weddings and then ended up in a divorce, she too had two weddings - one at the udeley Castle in Winchcombe in England and another one in India, where guests got to see not the India of call centers and software development but a country known for its turbans, elephants, saris, and curries.

Demi Moore, Ashton Kutcher relationship success secret

Demi Moore and Ashton Kutcher are excellent examples of older woman younger man relationship. That makes Demi Moore a leader of the cougars, as these women are called. But a recent interview with Vanity Fair, she was as surprised as all of us with the relationship. "If somebody would have said, 'OK, here is the prediction: You're going to meet a man 25 years old and he's going to see being with you and having your three kids as a bonus,' I would have said, 'Keep dreaming," she says.

The couple have a great relationship and also get along well with ex-husband Bruce Willis, who like Uma Thurman has been an excellent ex.

What surprised me most about the interview was that the couple wants to have children. Getting pregnant at 44 is nearly impossible without fertility treatment, but it might make sense considering that Kutcher is just 28 and has no children of his own, though he has been a good father for her three daughters.

And how does she keep looking good for her toyboy? She is one Hollywood celebrity with most cosmetic surgery.

Finally, what does it tell? That it is possible for a a couple with large age gap to have an excellent relationship and people should explore a relationship with someone younger or older if they are otherwise attracted to each other.
