Join us as we take a look at some of the celebrity couples out there who, through all of the glitz and glamor have managed to stand the test of time.

The couple got married in 1998 and since then, they have been inseparable. According to Gerber, the secret to their marriage is being friends, first and foremost. "We started as friends, and we remained? friends," he said. "You have to just keep that friendship and fun in the relationship."
