Perry popped onstage. (Splash News)Katy Perry was living out a teenage dream on Tuesday night. After performing for a huge crowd in Hollywood, following the premiere of her new movie "Part of Me," she partied the night away with none other than Justin Bieber, Selena Gomez, and Robert Pattinson. But before that, the pop star put on quite a show for her adoring fans who took over Hollywood Boulevard. Wearing a movie theater-inspired dress featuring red-and-white stripes, huge popcorn pieces, and film reels, Perry performed a bunch of her biggest hits, including "I Kissed a Girl" and her new song "Wide Awake."

Howdy, Maxwell. (Twitter)Jessica Simpson is clearly a proud mama. On Tuesday, the singer-turned-fashion mogul tweeted an adorable photo of her daughter Maxwell Drew, who was born on May 1. "Howdy friends," Simpson wrote in the caption, which accompanied the pic of her big-eyed (and big-lipped!) little girl in a red-and-white striped onesie. Just a few days before, the new mom tweeted a photo of her post-baby cleavage as she prepared to take a stroll around her neighborhood with the message: "Street legal?"

Before surgery. (Michael N. Todaro/WireImage)With her dad on June 4. (Twitter)Lauren Manzo's struggle to lose weight has been a major plot point this season of "The Real Housewives of New Jersey." Fans watched her try to diet and exercise — after her mother Caroline, who has struggled with her own weight, described her as "eight pounds of sausage in a five-pound bag" — but with little results, the 24-year-old opted to go under the knife. Manzo recently admitted that in September, she had lap band surgery, which has taken her weight from 185 pounds down to 155. "Something wasn't right with me," she tells Us Weekly as for why she decided to take such a drastic route. "I was depressed."

DJ Paris Hilton. (Splash News)Not everything is "hot" in Brazil. Paris Hilton debuted her new song at the Pop Music Festival in Sao Paolo, on Saturday, but it didn't exactly sizzle. The hotel heiress, dressed in a glitter-embellished black leotard reminiscent of something Lady Gaga wore in 2009, was met with a lot of jeers from the crowd when she took to the stage, but it didn't seem to faze her. "I love you guys so much!" she shouted into her bejeweled microphone as she sat in the deejay booth. "I've partied all around the world … to the best parties … but I've never seen anyone party like you guys do in Brazil."

Keough, rock royalty. (Miguel Reveriego/VANITY FAIR)He may have died years before she was even born, but Elvis Presley lives on in his look-alike granddaughter Riley Keough. The 23-year-old daughter of Lisa Marie tells the July issue of Vanity Fair that for as long as she can remember she's been a favorite with the King's many superfans. "Since I've been young, I get a lot of questions," says the model-actress, who's engaged to her "Magic Mike" co-star Alex Pettyfer. "I think it's really a sweet thing, and I've noticed that a lot of people tell me stories when I meet them about different Elvis shows they went to."

Perry and Brand. (Jason Merritt/Getty Images)In Katy Perry's new concert movie, "Part of Me," she's revealing a lot more of herself than just blue wigs, whipped-cream-spraying bras, and giant lollipop props. During her 11-month California Dreams world tour, the pop star was also trying to keep her new marriage to now-ex-husband Russell Brand alive — and all the heartbreak was caught by the cameras. "Being in love is a dream, but the reality is not like the movies," says Perry, 27, in the film which hits theaters on July 5. "There's a lot more compromise and sacrifice."

Fergie and her abs. (Russell James/SELF)There's no denying Black Eyed Peas singer Fergie (born Stacy Ferguson) has one of the best bodies in pop music — but even she has her insecurities. "I've learned to be more accepting of myself," she reveals in the July issue of Self magazine. "I'm 37, not 18, and I've got the lines to prove it." Fortunately, Fergie's got the body of an 18-year-old, but admits she has to work out a lot in order to keep her body toned and trim. "I want to be able to run around without worrying about sucking in my stomach!"

Aubry and Berry. (John Shearer/Getty Images)Halle Berry is paying quite a price for splitting from her baby daddy Gabriel Aubry. A family court judge has reportedly ordered the "Catwoman" star to pay her ex a whopping $20,000-a-month in child support for their 4-year-old daughter Nahla, of whom they share custody. According to TMZ, the decision came down on Monday during a meeting between lawyers for both the actress and the model. In comparison, Britney Spears was also ordered to pay Kevin Federline that much for their two sons in 2008 ... when he had sole custody. Aubry reportedly claims he needs that much money in order to properly care for Nahla as her mother does, like providing a nice home and clothing.
