What makes a good pair of jeans? A comfy waist? The right fit in the thighs? If you ask Heidi Klum, the answer is simple -- "It's very important to have a little bit of something fun on the butt."

At an event last week celebrating the launch of this seasons Heidi Klum by Jordache denim line, Heidi was all about the booty talk, saying, "The first thing girls do is turn around and look in the mirror and they look at what their butts look like. It has to look right and as perfect as possible."

We totally agree -- good butt jeans are a must-have. However, we're not entirely sure that everyone is down with the booty bling. Although, if we had Heidi's heinie, we might feel differently. With her tush, we'd probably bedazzle the bejeezus out of those back pockets.
