Instead of going the stuffy route like some of the other stars, Jen kicked things off with a joke, making Justin laugh behind her.

It's important to find someone who gets your humor.

Jen, 45, and Justin, 43, began dating in May 2011, and announced their engagement in August 2012. Their long engagement has been the subject of tabloid scrutiny, but it's clear from their appearance together at the SAG Awards that they are still going strong.
