Forget Magic Mike - it's all about Magic Channing these days.

Hollywood's newest heartthrob is riding a giant wave of success thanks to three hit movies in a row this year, The Vow, 21 Jump Street, and Magic Mike, the stripper flick based on his real-life encounters as a male dancer in Florida.

Along for the ride is wife-of-three years, Jenna Dewan-Tatum, who he met on the set of their 2006 dance flick, Step Up, when both were virtually unknown actors.

As the 32-year-old hunk gets used to his A-list status and all the attention and opportunities that come along with it, what are the chances that his relationship with his wife, whose career peaked when his was just getting started, can emerge unscathed?

If Hollywood history is any indication - things could go either way:

Mad Men star Jon Hamm is proof you can become an overnight heartthrob and still remain loyal to the person who loved you long before the whole world did. He's been with actress Jennifer Westfeld for the past 15 years and by all accounts, their relationship is as solid as ever.

Same goes for Grey's Anatomy star Patrick Dempsey, who married makeup artist Jillian Fink back in 1999 well before the career comeback that will forever have him known as Dr. McDreamy.

Then there are those couples who weren't so lucky, felled by rumours of career jealousy or the temptations that inevitably came along with superstardom.

Eminem's marriage to childhood sweetheart Kim Mathers was doomed amid the pressures of celebrity culture - despite the volatile couple trying the marriage thing twice. And there's a reason we can't remember the name of Josh Harnett's first love - it's because she got dumped after he became famous and started dating the likes of Kirsten Dunst, Scarlett Johansson and Amanda Seyfried.

Even stars in relationships with fellow celebrities often have trouble when the balance of power takes a dramatic shift.

When the world became obsessed with Megan Fox as its newest sex symbol four years ago, the pressures of fame saw her break up with Brian Austin Green and have a fling with her Transformers leading man Shia LaBeouf. (Obviously things worked out in the end because the happy hubby and wife now appear to be expecting their first child together.)

Jennifer Lopez left hubby Marc Anthony shortly after becoming People's Most Beautiful Person and enjoying a resurgence of popularity on American Idol; career jealousy was also said to be a factor in the divorces of Twilight actor Peter Facinelli and Jennie Garth as well as Project Runway host Heidi Klum and singer Seal.

If Tatum really is the good guy he's famous for playing on the big-screen, then the marriage should past this test with flying colours (provided his wife can keep up her confidence amidst all the people pulling at her man.) His reputation for keeping his ego in check, unlike many of his peers, could also increase the odds of it surviving.

If anything, Tatum may cling to his wife even harder these days, knowing she was there from the start and loves him and not the movie star.
