Brad Pitt and Angelina Jolie have been a superstar couple for several years now without tying the knot. Now they are getting pressure from some unexpected sources - their kids!

Pitt and Jolie have six kids together, and as they get older they're slowly putting more pressure on their parents to finally make it official. "Lately, Shiloh and Zahara have been chiming in, and Pax thinks it would just be the coolest thing ever to be a ring bearer," an insider said to OK Magazine.

So what do you think? Should the two finally exchange vows?
