Not only did Taylor Swift recruit half of Hollywood for her "Bad Blood" music video, but she can get them to join her onstage whenever she wants!

Last night T. Swizzle performed in London as a part of the British Summer Time festival at Hyde Park, and she brought Gigi Hadid, Kendall Jenner, Serena Williams, Karlie Kloss, Martha Hunt and Cara Delevingne to the stage when she sang "Style." When Cara appeared, Taylor told the crowd, "London, England make some noise for my friend ... One of your own, Cara Delevingne!" Love it!

Earlier in the day, the girls posted a bunch of selfies backstage, and they were also joined by A-list ladies Kate Hudson and Emma Watson! Not to bring up that feud with Katy Perry again, but we're pretty sure Taylor has way more celebs on her team!

Who knew?!

Model Chrissy Teigen is not only smokin' hot, she's a smoker! The sexy supermodel stepped out on the balcony of her hotel in Cannes for a cigarette break and surprised photographers and onlookers when she lit up. Teigen isn't known to be a smoker -- not of cigarettes, at least -- in fact, she Tweeted last summer, "Smoking is bad, but smoking in your car is next level shittastic gross." Funny enough, a follower Tweeted back "@chrissyteigen ever had to take a smoking hotel room? Uuughhhh." Uh, ugh is right!

Love won and Matt Bomer and Simon Halls are happy about it!

The couple arrived at LAX to board a flight Friday just after the Supreme Court decision legalizing same-sex marriage nationwide was announced. As pride flags flew on social media, the spirit on the street was just as high.

Back in cyberspace, Lena Dunahm implored boyfriend Jack Atonoff to "Get on it, yo." Neil Patrick Harris wrote: "It's a new day. Thank you Supreme Court. Thank you Justice Kennedy. Your opinion is profound, in more ways than you may know. #huzzah" Sean Hayes Tweeted: "What's better than a supreme taco from Taco Bell? The Supreme Court of the United States. Thank you for making marriage legal for EVERYONE today. Best birthday gift ever."

Selena Gomez appeared contemplative and focused during a hike with a pal on Friday after her Thursday-night run-in with ex, Justin Bieber, at Tori Kelly's album launch party in LA.

The "Good For You" singer, who just dropped the music video for her latest single, BTW, was in good spirits as she chatted with her hiking buddy. Gomez wore a black tank, tied up at the tummy, with black and blue Spandex workout pants and black Adidas trainers. Her hair was in a high ponytail and frankly, the girl looked damn cute. So cute, we have to wonder if Justin Bieber ever regrets not being with her ... on the daily. I mean, the hos he gets with don't hold a candle to Ms. Gomez. But alas ...

Justin Bieber hit NikeTown for the second time this week, on Friday, just as the video for the pop star's first EDM effort dropped -- "Where Are U Now," with Diplo and Skrillex.

After attending Tori Kelly's album launch party at The Nice Guy Thursday night, where ex Selena Gomez was also in attendance, Bieber took to social media to "sing" the praises of the fellow Canadian, Tweeting, "Good times last night. Hey@ToriKelly do u ever miss a note? She is crazy talented. Congrats on the album @ToriKelly. Loved when u sang oceans. Might of [sic] teared up."

Speaking of crazy talented, we love Biebs' latest single -- such a departure from his usual top-40 style ... What do YOU think?

Keeping it classy!

Tyga performed at club Envogue Geneve in Geneva, Switzerland last night, but after showing up late and only singing for about ten minutes, he caused some major drama.

According to sources for TMZ, the 25-year-old rapper was supposed to play for an hour, and when he left around 4am with his 17-year-old girlfriend Kylie Jenner, the owner ran out of the club and started yelling for Tyga, at which point a fight broke out. Kylie and Tyga were both already in the car, but after seeing the commotion Tyga jumped out, only to sneak back in after someone in the owner's posse flashed a gun.

Kylie hasn't commented on the situation, but Tyga tweeted earlier today:

"My Switzerland fans know whenever I show up I perform. I appreciate everybody that came out yesterday. Sum Club owners just think they own u just Kuz they pay u to come to they lil club for a hr. I ain't nobody slave. Don't harrass me and my people when we tryna chill n sh*t. Every since I came in the game in 2008 people tried to tarnish my brand.mislead who I am. I don't talk much.i hate during interviews and I hate the industry and what comes with fame," he continued. "I just wanna make music and be creative and be a dope ass n**** … Can't nothing stop what's planned. They can hate me but God gon show me love forever."

Kanye West covers the new issue of Q magazine, and while he talks about life as dad, he also opened up about losing his mother Donda.

In the emotional interview, Kanye reveals that he holds himself accountable for her death, and when asked what in his life he's sacrificed for his massive level of success, he simply said, "My mom."

Donda West died at the age of 58 after suffering complications from plastic surgery, which included liposuction and breast-reduction. "If I had never moved to L.A. she'd be alive," West lamented. "I don't want to go far into it because it will bring me to tears."

But someone who has brought a tremendous amount of joy into his life is his two-year-old daughter North. Kanye and wife Kim Kardashian are expecting a baby boy later this year, and the rapper declares that family is now his biggest priority. "While [Nori's] here in Europe I have to have six hours a day with her because otherwise I'll just work and she'll get scheduled around meetings," he said. "Instead, the meetings get scheduled around her."

Sounds like he's got it figured out!

Spread

These two can't get enough of each other!

Despite their 25-year age difference, Kris Jenner and Corey Gamble are still going strong. Earlier this week, the couple were caught canoodling at DailyMail's Cannes Lion yacht party in Cannes and now the gruesome twosome are spending the day shopping in Paris. Not a bad life for Justin Bieber's road manager! We have a feeling that Corey is charging all of his purchases to the Kardashian account!!

For their Parisian shopping excursion, the momager wore a sexy, lace-up getup and thigh-high peep-toe boots, which were previously worn by daughter Kim. Kanye West's wife was last seen wearing the plunging Givenchy catsuit to the Givenchy show during Paris Fashion Week in March.

The Kardashian girls loves to share their clothes with each other -- but we think the 59-year-old is a bit too old to be wearing her daughter's boob-baring skintight jumpsuit!
