Taylor Swift is gorgeous in yet another magazine. (Harper's Bazaar Australia)Perhaps we can expect a new Taylor Swift song about moving on? The singer/songwriter, who often writes about her own life, appears to have overcome the incident heard around the world when rapper Kanye West confronted her onstage as she won Best Female Video at the 2009 MTV VMAs. He thought Beyonce's "Single Ladies" clip should have won instead, and he might have had a point if he hadn't chosen such an inopportune time to express it. Regardless, the unscripted moment instantly spawned a catchphrase ("I'mma let you finish.."), countless headlines prompting Kanye to apologize, and of course a Swift-penned ballad called "Innocent" in which she claimed to have forgiven West.

Demi Lovato says she wants to be a role model now. Vivien Killilea/WireImageBefore she entered rehab, Demi Lovato's image was that of a squeaky-clean Disney star who little girls looked up to with the approval of their parents. She was a multi-talented starlet with a successful TV show, "Sonny With a Chance," and an up-and-coming music career that had her touring with her "Camp Rock" co-stars The Jonas Brothers. That was before she sought help at Illinois' Timberline Knolls in November 2010. Now, Demi admits that the entire time before entering the treatment program, she felt ashamed to be living a lie, and even thought, "Why would you want your kids to be like me?"

The revelations come as the 19-year-old, who has been open about her problems, offered fans a glimpse at her life today with the MTV documentary "Stay Strong: Demi Lovato," and an interview during the aftershow, in which she spoke candidly about her ongoing struggle. "I cannot tell you that I have not thrown up since treatment," she confessed to the network's SuChin Pak. "I cannot tell you that I have not cut myself since treatment. I'm not perfect. This is a daily battle that I will face the rest of my life."

Jennifer Lawrence covers Seventeen magazine.The highly-anticipated film "The Hunger Games" is shaping up to be a lot like "Twilight," another movie franchise you may have heard of. Besides the obvious — that it's based on a popular series of books and has tons of die-hard fans excited before they've even seen it — Jennifer Lawrence, 21, who plays the story's heroine Katniss, reveals to Seventeen that the two have even more in common. Here's a rundown:

Zac Efron hits the red carpet. (Michael Buckner/WireImage)We already know from his "High School Musical" days that Zac Efron can sing, but lately he's better known as the leading man from movies like the romantic drama "Charlie St. Cloud," the ensemble comedy "New Year's Eve," and the upcoming Nicholas Sparks tearjerker "The Lucky One." That doesn't mean the guy hasn't still got it, though. During an appearance Monday on "Conan," Zac showed he can still carry a tune when he belted out the Beach Boys song "Barbara Ann" a cappella with the red-headed comedian and the leader of his band, La Bamba.

After all, it was the show that made Justin Timberlake cry and Beyonce think she ruined Christmas for underprivileged kids. Now, five years after it went off the air, MTV is revamping the program — this time, without Kutcher as the main jokester (still, he remains the executive producer). Instead, celebs like Justin Bieber, Miley Cyrus, and Kelly Osbourne prank their own famous friends, Taylor Swift and Khloe Kardashian respectively, in the ninth season, beginning March 29.

Vanessa and Angela Simmons show off Pastry Shoes. (Pastry)When you're a part of the family that spawned entrepreneurial brothers Run-DMC rapper and reality star Joseph "Rev Run" Simmons and hip-hop mogul and Phat Farm founder Russell Simmons, ambition is instilled in you at an early age. At just 28 and 24, two of the Rev's daughters, Vanessa and Angela, who appeared on the shows "Run's House" and "Daddy's Girls," have been running their own brand of shoes since 2007, a fun, colorful brand of sneakers called Pastry Shoes, a brand now working with celebs like teen singers Cody Simpson and Jessica Jarrell as spokespeople.

In an interview with omg!, Vanessa — who, along with her sister, has appeared on the shows "Run's House" and "Daddy's Girls," — gave her famous relatives all the credit for making her and Angela the savvy business women that they are. "[Our family] makes us so ambitious and persistent in what we do and they lead by example," she revealed. "My dad always says 'Do your best and forget the rest,' and that's what we aim to do, just do the best that we can."

Demi Lovato (Macca/Todd G/Splash News)Demi Lovato (S Fernandez/Splash News)When Demi Lovato left rehab last January after completing 90 days for a variety of issues, including an eating disorder, depression, and cutting, the former Disney superstar debated returning to the spotlight. After all, it was the pressures of fame -- and the scrutiny that came along with it -- that landed her in the position she was in. "I thought, 'I'm exhausted, people don't understand and so many people are being negative towards me,'" the 19-year-old says in a new interview with UK's Metro. "It's hard. There are so many pressures that are put on you when you're in the industry. But I love doing it, I love singing. I don't want to give that up just because the going gets tough."
