Why do some celebrity couples end up as a train wreck, while others seem to withstand the test of time? Different strategies work for different power couples. For some, private time is the glue that cements them. For others, it’s a conscious decision to put marriage and family before work or making time for grand romantic gestures.

Check out what works for these four celebrity pairs:

Beyonce and Jay-Z: They are one of the world’s great couples. Jay-Z has an undeniable charm, a laugh to die for and a fantastic smile. The key to their happiness may lie in their equal success – both reportedly make around $80 million yearly. Celebrity couples have survived even without equal success, though, so what works for Jay-Z and Beyonce might be their commitment privacy. The couple is notoriously private about their relationship, keeping the magic between them and not opening up their bedroom to the world.

Faith Hill and Tim McGraw: Married since 1996 and some of the hottest entertainers on the country music scene, these two owe their success to spending time together. Even with their busy touring schedules and McGraw’s burgeoning movie career, they try never to spend more than three nights away from each other’s sides.

Jada Pinkett Smith and Will Smith: He’s the only actor ever to have scored eight consecutive films that grossed over $100 million domestically. Okay, so Will Smith is the biggest movie star ever. Jada’s also had some megahits, notably the Matrix series, and she’s taken turns as a writer and director. Still, Jada insists she would let her career go before allowing it to interfere with her relationship with Will. Maybe that’s why they’ve been together since 1997. Of course, it doesn’t hurt that this super-cute couple only seems to get better looking with age.

Heidi Klum and Seal: The former Victoria’s Secret model who stays involved with America’s Next Top Model, is known for her fabulous figure and gorgeous face. He’s known for his legendary singing voice and the uber-romantic ballad “Kiss From a Rose.” The pair met in 2003 and married in 2005. The fact that he’s English and she’s German never seems to be an issue for this playful pair, often caught in public frolicking with their four children. The romantic duo renews their wedding vows ever year on their anniversary.
