In honor of Elle magazine's 25th Anniversary this October, 25 women under 25 are being highlighted for their success at a young age. Amongst them are the four cover leaders: Amanda Seyfried, Megan Fox, Lauren Conrad and Gabourey Sidibe.
What are the best and worst things about turning 25 for Amanda?
"The best thing is, I'm happy," Amanda tells Elle. "The worst is that I'm scared; the scariest thing is that I know it can't be easy — the years to come."
As for Gabourey, she decided to celebrate her 21st birthday part five, instead of her 25th!
"Part of me thought it would be weird if people knew I was a grown-up playing a teenager in Precious. So I had a twenty-first-birthday party," she explains of her 25th birthday party. "We had drinks and went to a strip club called Shotgun Willie's."
But Lauren is loving her 20s because she can focus on her career!
"It's your time to be selfish; you still have freedom," Lauren says.
And she's happy with where she is at right now!
"I was never that girl who just wanted babies," she explains. "I wanted a career before all of that."
Megan, however, is all about married life right now!
"When I talk about my husband Brian Austin Green, I feel as if people roll their eyes," Megan explains. "It's like when you're 16 and order a martini, and the waiter says, 'Do you think I'm stupid?' They can't grasp that I'm old enough to be married."
