Ashlee Simpson and Pete Wentz. Olivia Wilde and Tao Ruspoli. Tony Hawk and Lhotse Merriam. Unexpected divorces seem to be the latest trend in Hollywood. With every announcement that a high-profile couple is splitting up (the above three were announced just this week alone), our belief in long-lasting love takes a depressing hit.

It almost makes us wonder what exactly we’ll be celebrating on Valentine’s Day if every relationship—even the ones we thought would last forever—crumbles in defeat.

But, there is a small glimmer of hope, and it’s represented in the celebrities who’ve stayed strong through the rollercoaster that is a Hollywood marriage. If love can prevail for them, then average couples have a shot at lasting unions, too. That’s why we look to the following 5 couples for love inspiration:

John Travolta and Kelly Preston — 19 years

John Travolta and Kelly Preston met in 1989 while filming The Experts and were married two years later in early September. They have a 10-year-old daughter, Ella Beau, and just welcomed baby Benjamin in November 2010. Unfortunately, they lost their oldest son, Jett, 16, two years ago when he suffered a seizure while on vacation, but the couple remains strong and dedicated to their family.

Kevin Bacon and Kyra Sedgwick — 22 years

After playing “6 Degrees of Kevin Bacon,” one knows just how many Hollywood women Bacon has worked with, but he’s remained true to wife Kyra Sedgwick ever since the two met on the set of the TV show Lemon Sky and later married in 1988. They have two kids, Travis, 21, and Sosie, 18, and still walk the red carpet arm-in-arm.
