Coachella

Taylor Swift and Travis Kelce were big time power-coupling at Coachella -- and had some other lovebirds tagging along to make it a big old group outing ... no third wheels allowed.

The pop star was out in force Saturday night in the desert -- and she had her BF by her side ... not to mention a newish-looking squad, including other couples ...  Justin and Hailey Bieber were in the mix -- as were Sabrina Carpenter and Barry Keoghan (SaBrarry?)

They were all leaving what looked to be the backstage area from Ice Spice's set -- where we'd seen them earlier -- and the whole crew trickled out almost in single-file line fashion.

Justin Bieber and Jaden Smith are still friends after all these years ... with Jaden grippin' Justin in a big hug and gettin' a smooch in return during Coachella.

The two music superstars met up Saturday during the music festival's busy first weekend ... and, JS decided to surprise his best bro by embracing him from behind.

Check out the clip ... Bieber's face lights up when he looks back and sees it's Jaden who decides to move around and go for a real embrace from JB in a VIP area at the festival.

Kesha's on the crap-on-Diddy train right now amid his legal woes -- changing some famous lyrics at Coachella to send a message ... namely, I don't mess with you anymore, Puffy!

The singer appeared as Renee Rapp's special guest Sunday during the music festival -- and sure enough, she sang her biggest hit 'Tik Tok' ... which starts out by name-dropping Diddy, but which she switched up in emphatic terms as she took the stage.

Instead of singing, "Wake up in the morning, feeling like P. Diddy" ... Kesha sang, "Wake up in the morning like f*** P. Diddy" -- and Renee was right there with her to sing it loud too.

Grimes' Coachella performance didn't go as planned ... plagued by constant stoppages she blamed on technical difficulties -- before she let off several frustrated shrieks.

The singer-songwriter took the stage on Saturday night out in Indio, CA, presumably ready to bring the house down ... though ultimately she couldn't keep the music up.

Check out the clip ... Grmies' show on the Sahara Stage is moving along just fine before an incorrectly timed transition throws the musician into a bit of a tailspin.

Taylor Swift and Travis Kelce decided to do a kissing tour of Coachella ... with the pair smoochin' in the middle of the crowd this time.

TMZ has obtained exclusive photos of this new passionate PDA session ... and, it's as clear as day -- these two lovebirds are absolutely crazy for one another!!!

Check out the pics ... Taylor and Travis are pretty out in the open here, fully invested in one another's lips -- without a care in the world as far as we can see.

Gwen Stefani y los chicos No Doubt incendiaron Coachella anoche... regresan juntos al escenario por primera vez en casi una década.

Gwen, el bajista Tony Kanal, el guitarrista Tom Dumont y el baterista Adrian Young se adueñaron del escenario de anoche, ofreciendo un set nostálgico y lleno de energía… realizando su primer concierto juntos en -- como Stefani misma lo expresó -- "¡nueve j*didos años!"

La banda tocó un set de 80 minutos cuyos fans disfrutaron al máximo... calificando el reencuentro como “icónica” y “una de las mejores actuaciones del año” en redes sociales.

Taylor Swift and Travis Kelce couldn't keep their hands to themselves Saturday night ... lockin' lips at Neon Carnival after engaging in some backstage PDA.

Video from inside Neon Carnival -- an invite-only rager sponsored by Liquid IV, Patron El Alto and Levi's -- shows the power couple immersed in their own little world, lips securely locked to one another.

Looks like they've both got drinks in hand at the mega-exclusive event ... though they're far more focused on using their mouths in a different way to take a swig.

Coachella's first weekend's still ragin', but some celebs chose to stay closer to home ... picking tuxedos and champagne instead of hard partyin' in the desert.

The 10th annual Breakthrough Prize Honors -- known in some circles as "The Oscars of Science" -- took place at the Academy Museum of Motion Pictures Saturday night and many of Hollywood's more "serious" stars stuck around for the festivities.

Kim Kardashian and her mom Kris Jenner took centerstage, of course ... wearing off-setting black and white ensembles while Elon Musk and Bradley Cooper kept it simple in traditional tuxes.

El viento aullaba por los campos de polo de Indio en el segundo día del festival de música y artes del Valle de Coachella y los grandes nombres del desierto se enfrentaron a vendavales y se adentraron en lo desconocido.

El día 2 trajo consigo grandes fiestas y actuaciones... ¡y Hollywood respondió a esa energía con sus propios looks! Teyana Taylor llevó la antorcha de los vaquero con un sombrero/bandana de la época de Bret Michaels y un caftán plateado transparente.

Lukas Gage lo mantuvo casual... pero de alguna manera le dio un toque de fraternidad a su look de moda festivalera... y Olivia Culpo hizo su peregrinación anual a las tierras sagradas de Hollywood con un sencillo vestido blanco para impulsar las plur vibes.

La fiesta posterior MÁS GRANDE del fin de semana, Neon Carnival, atrajo a todos los nombres más importantes del desierto... Ke$ha estaba armando un infierno mientras lucía con una camiseta vintage y un par de botas de vaquero clásicas. Amber Rose mostró sus curvas alrededor de la fiesta de Brent Bolthouse con un body verde... mientras que Paris Hilton continuó "viviendo en el desierto" con un jersey negro y algunos accesorios de cadenas cromadas.

Taylor Swift y Travis Kelce aparecieron por sorpresa en Coachella el sábado por la noche… acogidos por el backstage, mostraron su apoyo a los colaboradores de Tay.

La pareja fue vista detrás del escenario, abrazándose y bailando mientras tocaba la banda de su amigo Jack Antonoff, Bleachers.

Taylor también mostró apoyo a su colaboradora en “Karma”, Ice Spice, durante su set.

Taylor Swift and Travis Kelce made a surprise appearance at Coachella Saturday night ... getting cozy backstage while showing support for Tay's Collaborators.

The couple was spotted backstage hugging and dancing while friend Jack Antonoff's band Bleachers performed.

Traylor also showed support for Tay's "Karma" collaborator Ice Spice during her Coachella performance.

Gwen Stefani and the men of No Doubt set Coachella ablaze last night ... returning to the stage together for the first time in nearly a decade.

Gwen, bassist Tony Kanal, guitarist Tom Dumont and drummer Adrian Young took the stage last night, playing a nostalgic and high-energy set ... performing their first gig together in -- as Stefani herself put it -- "nine f***ing years!"

The band performed an 80-minute set and fans ate it up ... calling the reunion "iconic" and "one of the best performances of the year" on social media.

The winds were howling across the Indio polo fields for the second day of the Coachella Valley Music and Arts Festival and the biggest names in the desert faced the gales head-on into the unknown in true fashion!

Day 2 brought some big parties and performances ... and Hollywood matched that energy with some big looks of their own! Teyana Taylor carried the torch for the cowgirl caps with a Bret Michael's era hat/bandana and a sheer silver kaftan.

Lukas Gage kept it casual ... but somehow styled a frat-forward look into fest-fashion ... and Olivia Culpo made her yearly pilgrimage to the Hollywood holy-lands in a simple white dress to push the pure plur vibes.

The weekend's BIGGEST after-party Neon Carnival pulled in all the biggest names in the desert ... Ke$ha was raising hell as she rocked out with a vintage tee and a pair of classic cowboy boots. Amber Rose showed off her curves around the Brent Bolthouse bash in a green bodysuit ... while Paris Hilton continued "sliving in the desert" in a black jumper and some chromed-out chain accessories.

Yes, Coachella means Hollywood hits the desert for the music, performances and parties, but the stars also need a place to kick back, rinse off and show their hard-earned bods ... get ready to make a splash with the stars who love a good poolside hang in Palm Springs!

Soaking in the sun and having all kinds of fun, stars like Olivia O'Brien and Bretman Rock got into the swing swim of things in some sexy swimwear, and Kelsey Calemine proved that her poolside is her best side!

Smothered inside this cheeky-altered photo is a girl from the Bronx, New York City. Growing up, this rapping maven looked up to music icons like Lil Kim and Nicki Minaj. Put your best celeb-foot forward, and see if you can kick this photo edit to the curb!

If you didn't partake in her viral "And I'm Bad Like A Barbie" TikTok vid, you must've been sleeping under a rock!

She's icy, spicy and perhaps a bit pricy ... but Coachella budgeted for this queen to hit the stage both weekends and her fans are stoked!

Taylor Swift y Travis Kelce aparecieron este viernes en la noche por Los Ángeles para disfrutar de una cena romántica en lugar de ir a pasarlo bien a Coachella.

La querida pareja llegó hasta el Sushi Park, el lugar de moda de la ciudad, agarrados de la mano y viéndose guapísimos como siempre, mientras se dirigían al restaurante favorito de las celebridades.

Echa un vistazo a la foto, Tay está vestida de rojo, mientras que su hombre, Trav, fue con un suéter verde y pantalones cortos, una pareja muy sexy.
