Rumer Willis is on Lindsay Lohan's Side

"I haven't talked to her, but I wish her the best," Willis, 18, told PEOPLE at Thursday's BlackBerry Curve launch party in L.A. "I think there a lot of people that are supporting her. It's been kind of a crazy week, figuring it out, and figuring out a better way to be."

Willis, who has been photographed around L.A. with Lohan, says the actress's age, 20, should be taken into consideration. "I think it's definitely hard growing up in L.A. with all of the things that you have to deal with, and being so young," Willis said. "I think sometimes people don't realize the amount of pressure that can come."

"She's great, she's a really cool person," Willis said of Ronson. "She doesn't give a crap about what anybody else thinks about her, which I really respect."
