What's your love destiny? That all depends on the size of your pout, according to a study from the University of Leicester in England.

Couples whose lips are of a similar size and shape are more likely to stay together. The researchers found that 88 percent of happy couples had lips that mirrored each other's.

The study also showed that while men are instantly attracted to women with a luscious pout, they don't consider them marriage material. In fact, women with thinner lips are 57 percent more likely to have longer relationships than their pouty-lipped counterparts. Ditto for men: Thin-lipped guys are 39 percent more likely to have a longer-lasting relationship compared to men with full lips.

The size of your kissers can also reveal loads about your personality, say the researchers:

If you have...

A large mouth:

You're laid back, relaxed, easy, generous, and enjoys being in the middle of life.

A small mouth:

You're independent, strong-willed, precise, have great endurance and fighting spirit.

Full lips:

You're emotional, passionate, sensual, expresive, talkative and outgoing.

Thin lips:

You're efficient, achieving, disciplined, make clear and precise statements, and get on with life without fuss.

What your date orders at Starbucks says tons about his personality, according to Dr. Alan Hirsch, Director of the Smell & Taste Treatment and Research Foundation and author of What's Your Food Sign?

It may sound a tad far-fetched, but Dr. Hirsch has some science to back up the statement: His survey of 18,631 men and women revealed a strong correlation between the participants' drink preferences and their personalities.

Here's what his coffee order says about him:

Black coffee: He's aggressive, ambitious and independent

Café au lait: He's traditional and laid-back

Chai tea latte: He's shy and stubborn

Hot chocolate/ Mocha-flavored coffee: He's a dreamy romantic

Iced mocha: He's spontaneous and seductive

Iced tea with lemon: He's sexually shy and inhibited
