— Former OC star Mischa Barton is opening up about her struggle with depression after checking into a psychiatric hospital last fall. "As much as I get down, I'm an upbeat person," the 24-year-old actress says. "People always think of me as kind of a light in a room. I love to make people laugh." To cope, Barton uses music and literature to help stabilize her emotions. [Fit Perez]

Justin Bieber is quite the little daredevil. The 16-year-old "Somebody to Love" singer recently spent some downtime on the North Shore of Oahu, Hawaii — but he proved to be anything but a beach bum! Clad in blue swim trunks, Bieber crawled atop several jagged rocks before cliff diving at Waimea Bay. [Wonder Wall]

Beverly Hills, 90210 alum Shannen Doherty knows what it's like to have a bad girl image in Hollywood — which is why she hopes Lindsay Lohan can turn her life around before it's too late. "I actually think Lindsay is really talented," the 39-year-old actress says. "You know, you watch somebody who is that talented, who obviously has a lot of family issues, which a lot of people would say is the root of her problems. I was able to make mistakes, learn from them and grow as a human being, because I have a very strong family…If I did stumble and fall on my face, I could remember who I am and how my parents raised me, and always get back to that."

KE$HA is firing back at critics who dismiss the pop star as a below-average singer. "I accidentally read a review, and it was really positive, but at the end it said, 'We don't really know if she has the best voice.' Which is bulls**t! That's the one thing I'm most confident about," the 23-year-old singer tells Seventeen's November issue. "I don't have the best body in the world, but I know for a fact that I have a really good voice." [Just Jared]

— Did Kristen Stewart's Welcome to the Rileys director Jake Scott diss his leading lady? "She's very vulpine — very wolfish — and wily, kind of twitchy," he said of the 20-year-old actress. "Directing her is kind of like wrangling a herd of cats." [Pop Sugar]
