Before the Screen Actors Guild Awards air this weekend, ET is taking a look back at some of the most amazing moments we've captured at the show that have never aired before.

1. When Angelina Jolie Had to Do Her Own Hair

The actress won Best Actress at the 1999 ceremony for her role in Gia, but before scoring that accolade, she adorably told ET that she was "a mess." "I curled my own hair today, and I had to get four different sets of curlers," she admitted backstage. "I had half my head done. I ran out of curlers. I had to call my mom, and she had to go like Thrifty to pick up curlers, and I made it through and I'm here!"

2. When Reese Witherspoon Cried

In 2006, the actress won her first SAG award for her leading role in Walk the Line. "It's just a lot about where I'm from... I'm going to cry again," Witherspoon said backstage, cradling her award. Later that year, she went on to take home the Oscar for Best Actress for her portrayal of June Carter.

3. When Julia Roberts Couldn't Keep It Together

America's sweetheart was still shaking when she walked off the stage in 2001 after being awarded for her leading role in Erin Brockovich."I'm just overcome," she told ET.

4. When ET Met Jennifer Lawrence's Parents

In 2013, J. Law won for her leading role in Silver Linings Playbook, and she had her parents, Gary and Karen, there to help her celebrate. "I feel like I've got Secretariat in the derby," Gary gushed. "She's stayed strong and true to herself," Karen added with tears in her eyes. "That's what makes me proud."
