At a star-studded London Fashion Week event Tuesday night, Freida Pinto and Dev Patel made no attempt to hide their off-screen romance.
Arriving arm-in-arm to the Burberry Prorsum Spring/Summer 2010 show at London's Chelsea School of Art and Design on Tuesday night, the Slumdog Millionaire
actress wore a short, figure-hugging dress from the designer's current collection, much to the approval of her boyfriend.
"He likes me in short dresses," she said.
"No, Mummy. That's a lie!" Patel quickly added for the sake of Pinto's mother, laughing.
Sure, there were Hollywood A-listers like Gwyneth Paltrow
, Liv Tyler
and Victoria Beckham
sitting close by, but Patel, 19, only had eyes for his girlfriend and onetime costar
, 24, as they sat holding hands during the show, whispering in each others' ears.
After congratulations with the Burberry creative director backstage, the couple hopped over to the after party, where they enjoyed a live performance by Brit band The Kooks.
