The famous teen in action. (Splash News)It's not easy being Justin Bieber! The 18-year-old pop star, who's become one of the biggest names in Hollywood since he was discovered on YouTube in 2007, talks candidly about the downside of his phenomenal fame in a new interview with Vibe magazine. "What does that really mean, 'to be famous'?" Bieber mused. "In general, fame can tear you apart, so you can never really feel like you're famous. When people start acting like they're famous, that's when they start losing it." For the record, Bieber and his famous girlfriend Selena Gomez are often photographed doing pretty normal things, like eating at IHOP, catching a movie, or visiting his family in Canada, although they've also been seen taking a helicopter ride and renting out the Staples Center in L.A. for a private screening of "Titanic."

Kristen Stewart and Rupert Sanders (Getty Images)Could Kristen Stewart and her "Snow White and the Huntsman" director Rupert Sanders be working together again ... soon? The married 41-year-old married Sanders and the 22-year-old actress were photographed kissing and canoodling on July 17, which prompted Stewart to issue that now famous public apology to her boyfriend and "Twilight" co-star Robert Pattinson. Sanders also apologized to wife Liberty Ross and his two young children. (Calm down, Twi-hards! I know it makes you mad just thinking about it….) Then Wednesday, the usually reliable Hollywood Reporter wrote that Stewart had been dropped from a starring role in the much talked about sequel to "Snow White," which brought in $389 million worldwide at the box office.

It's a summer of bold decisions for Miley Cyrus! After the 19-year-old raised some eyebrows in June when she announced she's planning to marry Australian actor Liam Hemsworth, she's completely changed up her look, debuting a platinum blond, super short, very edgy new hairstyle.

Lucy Hale (George Pimentel/WireImage)"Pretty Little Liars" actress Lucy Hale has revealed that like so many starlets before her, she's struggled with an eating disorder. In an interview in the September issue of Cosmopolitan, the 23-year-old who began her career on the short-lived reality TV competition "American Juniors" when she was 14, candidly explained her battle. "I've never really talked about this, but I would go days without eating," Hale told the magazine. "Or maybe I'd have some fruit and then go to the gym for three hours. I knew I had a problem ... It was a gradual process but I changed myself."

Unfortunately, this is a story we've heard too many times.

No wonder Justin Bieber and the former "Marky Mark" Wahlberg have become such bros! Both began their careers as terribly dressed pop stars who later set their sights on acting. But while Wahlberg's on-screen credits include respected performances in critically acclaimed movies like 2010's "The Fighter" and 2006's "The Departed," 18-year-old Bieber's resume so far is limited to his music videos and a couple of episodes of "CSI." (Last year's documentary about him, "Never Say Never," doesn't really count.)

Kristin Cavallari (RevolutionPix/PacificCoastNews.com)"The Hills" gang is all grown up! And to prove it, the former MTV show's resident bad girl Kristin Cavallari, 25, just gave birth to her first child, son Camden Jack Cutler. Dad is Cavallari's fiance, Chicago Bears quarterback Jay Cutler, 29. "We are thrilled to welcome Camden Jack Cutler into the world," Cavallari wrote on Twitter on Wednesday. "He was born this morning weighing 7lbs 9oz. Everyone is doing great!" According to what Cavallari's said in the past, a problem-free birth is a sign that more little Cutlers will be on the way soon. "We're talking about the possibility of having another kid right away and then getting married so we can have two kids close in age," she revealed to Glamaholic magazine in March. "We want four kids, so we're thinking have one more, then get married, then have two more, but we'll see. It all depends on how the first one goes."

(Indigo/Getty Images)Justin Bieber's mop top has been the butt of many jokes over the years, and he can not only take it — but he can apparently dish it out, too. In an interview with Rollercoaster magazine, the "Boyfriend" singer called out none other than his royal highness, Prince William, for his thinning hair. "I mean, there are things to prevent that nowadays, like Propecia," Bieber, 18, told the U.K. publication. "I don't know why he doesn't just get those things, those products. You just take Propecia and your hair grows back. Have you not got it over here?"
