Sandra Bullock and Melissa McCarthy teamed up to hype The Heat today at CinemaCon in Las Vegas. The pair play law enforcement agents who don't exactly see eye to eye in the upcoming buddy comedy, which was directed by Bridesmaids' Paul Feig and hits theaters in late June.

We spoke to Sandra, Melissa, and Paul this morning about the broadening opportunities for female-driven comedies — which Paul has referred to as "bramances" — that he helped champion with Bridesmaids. Sandra also described her bond with Melissa as a true "love connection," and Paul said his stars instantly hit it off when they first got together to rehearse, chatting about their kids and becoming fast friends. Stay tuned to catch our full interviews with the trio!

Last night's A/X Armani ExchangeNeon Carnival at Coachella brought the stars out for a night out in the desert. The carnival-themed event, held at an airport hangar, lasted early into the morning. During the festivities, Julianne Hough, Alex Pettyfer, and Ed Westwick took turns throwing darts, while Emma Roberts hopped on the giant slide. Vanessa Hudgens and her boyfriend, Austin Butler, also took advantage of the rides and took a spin on the bumper cars, while Alexander Skarsgard was spotted making the rounds solo. One unexpected guest at the bash was Clint Eastwood, who played carnival games, sipped beer, and stopped to take some photos with fans.

Today's H&M Loves Music pool party was held at the expansive Merv Griffin Estate just outside of Palm Springs. The bash was the first such event the global fashion brand has thrown in conjunction with Coachella. The festivities featured paddleboat rides and ping-pong tables, carnival snacks including popcorn, cotton candy, and churros, and a live poolside performance by Santigold. Santigold hit the stage late in the afternoon and played some of her biggest hits, including "L.E.S. Artistes," for the crowd. During the soiree, we caught up with Sophia Bush, who was lounging under an umbrella with a group, and spotted Darren Criss taking a turn on the paddleboats. Diane Kruger and Joshua Jackson also arrived with friend and designer Jason Wu and relaxed by the pool.

Later on, Diane and Joshua transitioned to the Coachella festival itself, where they shared a few kisses in the VIP sections as bands played. Several famous couples have been making the rounds at the festival this year. Robert Pattinson and Kristen Stewart were at Coachella last night, Michael Polish and Kate Bosworth spent yesterday afternoon checking out bands including Beach House, and even Hilary Duff and her husband Mike Comrie made their way out to the desert to take in the first of two Coachella weekends.

Today, the Lacoste L!ve Coachella party continued for a second day, with Elijah Wood manning the turntables for the crowd. Yesterday, Katy Perry stopped to pose for photos with the classic Lacoste alligator as she arrived to the event. Katy, who has been making the rounds at the festival this weekend, donned a tropical-themed bra top and miniskirt by Dolce & Gabbana to the soiree; she even carried a matching pineapple purse. On Friday night, she took in some music at Coachella with her friends Kristen Stewart and Robert Pattinson. Katy was one of several recording artists and musicians at the Lacoste event over the weekend, where Alexa Chung played DJ and Rita Ora relaxed in the shade. Meanwhile, Chris Pine, Victoria's Secret Angel Alessandra Ambrosio, and The Carrie Diaries actress AnnaSophia Robb lounged in a cabana together during the hot desert afternoon, and brothers Joe and Nick Jonas stayed cool in hats and shades as they made the rounds.

We'll be on the ground at Coachella all weekend, bringing you the latest from all the parties and the festival, so be sure to follow POPSUGAR on Twitter to stay up to date on all the action.

Kate Bosworth and her director fiancé Michael Polish are spending their second Coachella together and kicked things off yesterday with some fun and PDA on the festival field. Kate and Michael met when they worked together on the movie Big Sur, and got engaged last September, just a few months after last year's Coachella festivities. The pair tweeted about taking in Beach House's set during their afternoon at the grounds. The engaged couple held hands and wrapped their arms around each other as they checked out bands but were also spotted taking pictures with some young fans and catching up with a few friends.

Yesterday, Kate looked festival-ready in a suede, eyelet tank top and matching shorts — check out our roundup of all the stylish celebrities at Coachella for details on her look and many others'.

Last night, Bono cohosted a Coachella party that drew stars ranging from John Legend to Joe Jonas. Bono's clothing company, Edun — which he cofounded with his wife Ali Hewson in 2005 — teamed up with Diesel to throw their Studio Africa soiree on the first official night of the 2013 festival. The brands launched the Studio Africa project this year as an effort to spotlight fashion, music, and other arts from the continent.

Solange Knowles played DJ for the night at yesterday evening's bash, and Congolese-Belgian musician Baloji performed for the crowd. While plenty of the attendees have a musical pedigree of their own, such as John, plenty of actors and other celebrities hit the party, which was held at a private estate in La Quinta, CA. John and his fiancée, Chrissy Teigen, were spotted hanging out with stylist Brad Goreski, while Kellan Lutz, Theresa Palmer, Joe Jonas, and Mad Men's Jessica Paré rounded out the VIP crowd.

Katy Perry, Julianne Hough, Sophia Bush, and Eli Roth were among the stars who attended this afternoon's Shop Bazaar party at The Parker in Palm Springs. We stopped by the Coachella weekend bash, which was hosted by Harper's Bazaar and drew dozens of stylish guests. The event even featured a pop-up boutique where guests could shop for swimsuits, jewelry, and beach towels to complete their festival looks. As the afternoon went on, DJ Mia Moretti took a break from the turntables to take photos with her friend Katy Perry, who is a fixture at Coachella each year. A recently single Julianne Hough also hung out by the pool and shared a few laughs with a group of female friends. After the party, we spotted Sophia at the field, where she checked out the bands Passion Pit and Tanlines.
