Success. Carrey is one of the highest-paid actors in Hollywood, earning $25 million for 2003's Bruce Almighty. He's also won a couple of Golden Globe awards for his more dramatic performances in films like The Truman Show and Man on the Moon. For her part, McCarthy was Playboy's 2003 Playmate of the Year, but her recent TV work has gone relatively unnoticed. She's spent her time instead writing books about pregnancy and motherhood and speaking out as an activist against child vaccinations. Recently, however, she landed her own talk show sponsored by Oprah, which is always a recipe for success.
Attractiveness. As mentioned above, Jenny was a Playmate back in the day, and she looks just as hot now as she did then (Botox helps). Jim isn't bad on the eyes, but he's never been known for his looks as a leading man in movies.
Popularity. Last month, around 673,000 people searched Google for information about Jim, and 450,000 searched for Jenny -- enough to put them in the top half of our most popular couples.
Staying Power. Both of these celebs love dating in the Hollywood circuit. Jenny dated her manager Ray Manzella before she married actor John Mallory Asher in 1998. They split in 2005. Jim is no less guilty: He was briefly married to a waitress before he tied the knot with Dumb and Dumber costar Lauren Holly in 1996. Then he moved on to Renee Zellweger and, later, his massage therapist. As happy as McCarthy and Carrey have seemed for the past few years, their histories suggest a tendency to stray -- though Ellen Degeneres did her best to pressure them into marriage.
Compatibility. Jenny's a Scorpio, and Jim is a Capricorn, so the stars have aligned for this couple. They're mutually supportive of one another, and her depth helps to bring out his own hidden emotions. Does this mean we'll see Carrey in some more dramatic roles?
