Chrissy Teigen & John Legend: Miles Teller Is "Awesome"  
?"Oh my God, he's so awesome!"  
model Chrissy Teigen gushed after she and her husband, R&B singer John Legend met the 28-year-old Whiplash actor at the opening of The Samsung Studio LA in West Hollywood on April 28.  Teigen broke the ice when Legend introduced himself to Teller by telling her spouse to "stop acting so cool" and then explaining to Teller that her husband is "a huge fan" of actor and musician. Teller told Overheard that he'd come straight to the event -- which drew a crowd that included model and "Blurred Lines" music video star Emily Ratajkowski, actor Michael B. Jordan and pop singer Joe Jonas -- straight from wrapping the film Arms and the Dudes with Jonah Hill. Teller said the soiree, in which the VIP crowd was checking out Samsung's latest gadgets, including the Galaxy S6 Edge, before catching sets by DJ Kiss, DJ MOS and The Killers frontman-gone-solo Brandon Flowers, was his "date night" with girlfriend Keleigh Sperry. Legend and Teigen danced to Run-D.M.C.'s "It's Tricky" and, at the end of the song Teigen planted herself on the singer's lap to take a breather. Flowers' set included Killers' fan favorites "Mr. Brightside," "Crossfire," "Only the Young" and a cover of Robert Palmer's "Simply Irresistible."  Also on hand to catch the performance was Taken actress Maggie Grace, who revealed that her fiance,  How to Make Money Selling Drugs director Matthew Cooke popped the question to her in February on an airplane, "halfway between heaven and earth," she said.

The singalong, a tradition at the 22-year-old event, took place after Ora performed a set that included “I Will Never Let You Down” and “Black Widow.” Ne-Yo sang a number of his hits, including “She Knows” and “Miss Independent.” Twelve-year-old YouTube rapper Matty B also performed. Paris Hilton -- who, according to her mother, will be DJ’ing at the Wynn Las Vegas Resort and Casino after the Floyd Mayweather-Manny Pacquiao fight on May 2, snarled traffic at the hotel’s valet parking station at the end of the night by spending 15 minutes looking for clothing in the back of her SUV while a row of cars and their fuming drivers waited behind her.
