Plus, more of the week’s best photos tweeted by the stars. PinkA fan actually snapped this photo and Pink loved it so much she retweeted it. “Great pic:)” she tweeted back. The gorgeous candid of the singer doing some high-flying stunts was taken in Perth, Australia. Hopefully, she’s more careful doing aerial choreography; in 2010, she was injured after falling out of a harness during a show. The rocker is Down Under for her Truth About Love tour, marking her return to Australia for the first time in three years. CiaraOld Hollywood glamour! Ciara and her beau, Future, took a quick pic looking all dolled up backstage at Late Night With Jimmy Fallon. Ciara and Future were on hand to promote Ciara’s recently released self-titled album and to perform their song, “Body Party,” which is sitting pretty at No. 3 on the Billboard R&B charts. Certainly both looked picture perfect. Mariah CareyLast week, Mariah Carey tweeted a picture in a hospital with the dislocated shoulder she suffered after falling on the set of a music video with Jay Z. It looks like not even an injury can put a damper on Mimi’s style. She showed up to perform at the New York Philharmonic in a sparkly gown and matching blinged-out sling looking fabulous. Nicki MinajNicki Minaj sported a more subdued look than normal in this pic. No crazy hair colors, makeup, or candy-colored clothes. Minaj still shines in a sleek, blonde ’do and white tank, topped off with some serious Chanel jewelry. “On the set of PYHU ~ cmn soon. Swizz. Wayne. Ross. Chain,” tweeted Minaj. Sounds like another collaboration is in the works. Joe RoganA kettle weight is good for exercise, but how many calories does taking selfies burn? The shot is a little blurry, but since it was taken during a workout, Rogan gets a pass. Rogan is a longtime UFC commentator as well as a comedian, so it makes perfect sense that he’d want to keep in good shape. He’ll be starting a new gig hosting the Syfy channel’s Question Everything, a show about unusual theories, at the end of July. Rita OraMaybe they’ll take a trip to a thrift store? The British songstress met up with Seattle rapper Macklemore and seemed to bump into each other while performing at the 2013 Yahoo Wireless festival. Macklemore wasn’t the only performer Ora had her eye on at the festival. She was seen chatting with Jessica Biel while she was watching husband Justin Timberlake perform and reportedly expressed some interest in doing a duet with Timberlake. We’ll see if Biel passes the message along. Candice SwanepoelThe Victoria’s Secret angel posed in lingerie and glittery masks with a friend after going through hair and makeup. Candice Swanepoel and the other angels have been traveling around the country as part of the Victoria’s Secret U.S. of Angels Summer Swim Tour. Her last stop, in Seattle, was a huge success, and she posed for pictures with fans and signed autographs. Flo RidaFlorida rapper Flo Rida (very clever) posted this picture with the caption “#cantbelieveit on the way!” Maybe this is a hint toward a music video for the track off his latest album, Can’t Believe It. The song is yet another collaboration between Flo and Pitbull, much like Pitbull’s 2008 song “Move Shake Drop,” featuring good friend Flo. Jim Gaffigan“Me, Tinkerbell and her ‘boyfriend’” tweeted comedian Jim Gaffigan while enjoying a day at Disneyland with his son. Gaffigan is promoting his memoir, Fat Dad, which has sold so well that he’s already been in talks to publish a second book. Nina DobrevVampire Diaries star Nina Dobrev is not only beautiful, but educational, too. After a stylist on set burned herself while working on the fifth season of the supernatural soap opera, Dobrev came to the rescue with some La Mer cream and showed her concern in this twitpic. “MomaNina knows best! LA MER was 1st created by a NASA scientist 4 Burn victims!” she tweeted. Thanks for the info, safety first! Tyler the CreatorTyler may not be doing that right. The rapper and member of sketch-comedy group Loiter Squad posted for this bizarre image of inventive outdoor smoking, but didn’t provide much in the way of explanation. He’ll appear on Doris, the upcoming album by bandmate and fellow Loiter Squad member Earl Sweatshirt. Gabrielle UnionGabrielle Union knows how to color block. The actress posed in a sunny frock paired with deep blue heels with boyfriend Dwyane Wade, who was considerate enough to dress in all white. The lovely couple stepped out this week to walk the red carpet of the ESPY Awards and, like in this snapshot, they were one stylish couple.
