Alec Baldwin plays a guessing game, Kevin Spacey shows up for tennis, plus more of the stars’ Twitter photos from this week. Gamers flocked to this year’s E3 Expo at the Los Angeles Convention Center, and Jack Osbourne looked excited to join them in this Twitter pic. He interviewed videogame designers and even Snoop Dogg for Fuse News as a senior correspondent for the show—a gig he landed earlier this year. “Future hat head courtesy of my new best friend @russellcrowe,” wrote Jimmy Fallon about this snapshot he tweeted to fans. Russell Crowe joined the host of NBC’s late-night talk show to promote his Man of Steel film earlier this week, and choreographer Jamie King taught the two how to bust out some Michael Jackson dance moves on the show. “Mom and daughter looking glam!” Ramona Singer captioned this Twitter photo. The cast member of Bravo’s The Real Housewives of New York City has been on the show since its first season. Everyone deserves a treat after a hard day’s work, including Carly Rae Jepsen! The “Call Me Maybe” singer wrapped up a press day in Toronto and took along some cotton candy as a treat in this Twitter pic. Soon after, she headed to New York to perform in ABC’s Good Morning America summer concert series in Central Park. Throughout the week, Usher gave fans a behind-the-scenes look into his life through his Instagram account as he prepped for the live performance of his new single, “Twisted,” on NBC’s The Voice. “Getting taped up now..we're getting #VoiceTwisted later!” Usher wrote about the snapshot he tweeted to fans. He went from song coach to R&B superstar within moments during his song. “And the judges have arrived,” host Mario Lopez tweeted about this photo showing the judges of Fox’s The X Factor among an audience giving them a standing ovation. The show began its auditions in New Orleans this week. In a sleek THEIA dress, comedian Kathy Griffin joined Joan Rivers for E!’s Fashion Police to celebrate the host’s birthday, as seen in this Twitter snapshot. Singer Adam Lambert also made a guest appearance to partake in the festivities. “Love my boys sooooo much,” LeAnn Rimes captioned this selfie with her buddies. The country crooner released her latest album, Spitfire, earlier this month. “I felt like I’d had tape over my mouth for a while,” Rimes said about the story behind the album title, in Parade. “Once I ripped it off, emotions came pouring out of me in rapid fire.” The former NBC 30 Rock star had his Twitter followers guess his location in this selfie. Baldwin and his wife, Hilaria, trekked to Washington, D.C., this week and revealed that they were on the gala chair committee for the Smithsonian’s upcoming yoga exhibit. It’s a wrap! Actress Jessica Alba had her last day on set in Colorado for film Dear Eleanor (about a cross-country trip) and tweeted this picture of herself with co-stars in 1960s garb. The film was directed by Kevin Connolly (Entourage) and produced by Leonardo DiCaprio’s (The Great Gatsby) company. Actor Kevin Spacey (House of Cards) took a break from watching Andy Murray and Nicolas Mahut’s tennis match at Queen’s Club to take a Twitter selfie during a rain delay. This was Murray’s return to the sport after a back injury.
