Julia Roberts may have dropped the F-Bomb on Tom Hanks at this week’s Film Society of Lincoln Center Gala Tribute honoring the actor, but that wasn’t the only way she kept things colorful. The Pretty Woman looked elegant in her Dolce & Gabbana dress and Me&Ro earrings — except for a light pink streak at the nape of her neck that’s had us puzzled for months. And she finally shared with us what it’s all about. “It’s been there since last October,” Julia told PEOPLE.com on the red carpet, explaining that she added the streak simply because, “My kids like it!” And it looks like she may have started a trend. Costar Adrien Brody turned up at the event with tufts of blue hair at the back of his coif. “I did a car race recently,” he explained. “They were my racing stripes.” Tell us: Would you ever change-up your look by adding a little vivid color to your hair? –reporting by Jeffrey Slonim
