So this is what Lady Gaga looks like fully clothed ...

The actress covered up (to an excess) to greet fans on Saturday at the Chateau Marmont. Mother Monster brought cookies and soda (in lieu of milk) for the occasion, while her Little Monsters gifted her red roses. The gracious pop star posed for pictures, signed autographs, and gave away kisses.



Although she looked graceful and sophisticated, she was probably having a heat stroke under the West Hollywood sun in her thick black and white turtleneck and black pants (she also wore mismatched heels). But, in true Gaga fashion, she didn't show it. The songstress seemed elated to be with her adoring fans, who have already made her single "Applause" -- off her hotly anticipated album ARTPOP -- hugely successful.

Robert Pattinson aggressively shoved a security guard he mistook for a photographer while exiting a club in West Hollywood on Friday night.

The actor was attending a Bobby Long concert with friends. He looked a tad tipsy while leaving the Troubador and navigating through the sea of photographers. He then suddenly pushed a man's face away with his palm, shoving him backward.

Oddly enough, RPatz was smiling ear to ear during the altercation. Maybe the guard made a comment about Kristen Stewart. What else could have made him so gleefully angry?

Justin Bieber has apparently moved past partying with his peers to partying with Jay Z.

The pop sensation hung out with the rap legend on Friday at a Miami nightclub. He Instagrammed a shot of himself sitting nonchalantly beside his gold chain buddies Jay and comedian Kevin Hart. "Last night with the fellas," he captioned the photo. If they are indeed "fellas," Jay just lost what little street cred he had left.

In another photo, the Biebs flashes a smile and gang signs behind Jay and Jermaine Dupri.

Bieber told Teen Vogue in April that he is modelling his career and his means of dealing with the press after Jay Z. "I don’t need to address every speculation," he said. "Remember when Cam’ron dissed Jay Z? Jay Z didn’t even respond. Why didn’t he respond, because he’s Jay Z."

Let's hope his career is just as prosperous.

Despite her paternity suit drama, Kourtney Kardashian and her family were in high spirits while running errands Saturday in Calabasas.

Model Michael Girgenti's filed a lawsuit against the eldest Kardashian, alleging that he's Mason's real father. The reality star therefore released the results of Scott Disick's paternity test to E! on Thursday, proving that her longtime boyfriend is indeed her three-year-old's dad. She also released a statement to end to the speculation.

After three-and-a-half years of rumors and lies being spread by an individual I met briefly at a photo shoot, I am setting the record straight that Scott is Mason's father. While it saddens me to have to address these ridiculous lies — especially when the truth was never in doubt — this story must be put to rest.

However, Michael, who first met Kourtney on a photo shoot in 2008, is now claiming that the results were fixed. In the suit, he alleges to have slept with Kourt a year after the shoot when she briefly broke up with Scott. He says Mason was born nine months later.

We just can't keep up with Rihanna's constantly evolving hairstyle!

The singer rocked a mullet -- pixie in the front, pig tail in the back -- on Friday while jetting off to Miami Beach. She Instagrammed photos of herself goofing off with her posse (read: straddling several friends' laps) on board the private plane. Only Rihanna could make a mullet look sexy.



RiRi also looked fashionable in a River Island printed tunic with slits on the side that tastefully bared some skin. She paired the extra long top with matching leggings. Before she put on the funky get-up, she posted a photo of herself lying in bed with the underwear that would later peek out of her pants.

Once on sold ground, she rubbed elbows with Jay Z and Kevin Hart, who then hung out with Justin Bieber. It's such a small word/Miami night scene.

Halle Berry is one lucky lady!

The very pregnant actress celebrated her 47th birthday with her adorable daughter Nahla and new husband Olivier Martinez.

The gorgeous star ditched the makeup and donned a flowy white dress to dine with her family at Craig's in West Hollywood. Her actual birthday was on August 14. Olivier carried Nahla as she held on to her mom's colorful present. We wonder what they bought the woman who has everything.

Regardless of how old she is, she will always be ageless in our book.

Lindsay Lohan may have dropped some bad habits, but she apparently still smokes ... at the worst possible times.

The actress Instagrammed a photo of herself on Friday brushing her teeth while holding a lit cigarette in the other hand. Ummm, that kind of defeats the purpose of brushing, Linds! Unfortunately, we've seen her do much more bizarre things in the past.

"Oh to brush my teeth on set @ #workhard -never felt so good! Lol," she wrote in the caption. Lilo is filming a guest appearance on HBO's Eastbound & Down for its upcoming fourth and final season. She reportedly plays an adult version of Kenny Powers' illegitimate daughter and will be shooting a wedding scene set in the future.

Aside from cleaning her teeth, it looks like she's also cleaning up her act. She crated a new website (lindsaylohan.com) on Friday, featuring photos, videos, and a style blog. Let's hope this guest spot helps relaunch her once thriving career.

Jennifer Lopez is still Jenny from the American Idol block.

After months of speculation, her boyfriend Casper Smart confirmed that J.Lo will be returning to the reality series next season.

The dancer was promoting his new nuvoTV show A Step Away when he told E! News Jen was coming back to Idol. He mistakenly thought Fox had already made the announcement.

However, Fox president Kevin Reilly did say that the network had made Lopez an offer. "Jennifer has been a close part of the show all along … there have been discussions there," he said at the Television Critics Association summer press tour.

Lopez, who served as judge in 2011 and 2012, has reportedly signed a $15 million contact. She will join another familiar face -- Keith Urban -- for AI's 13th season.

Former contestants Jennifer Hudson, Kelly Clarkson, Clay Aiken, and Adam Lambert have all been courted to replace Mariah Carey, Randy Jackson, and Nicki Minaj. Black Eyed Peas frontman will.i.am, Katy Perry, Miley Cyrus, and Fergie are also allegedly in the running for the final one or two slots.

Auditions are underway for Season 13, which premiers in January.
