Stephanie, who rose to fame in US reality show The Hills, was pictured at the Rollerfest Pampering Day, held by Sleep-In Rollers, in Jewel bar and club in London.
Wearing a pretty floral sundress teamed with funky studded Converse trainers, Stephanie was all smiles as she posed for the cameras.
She wore her blonde hair in big curls and topped off her look with thick eyeliner, lashes and a pale pink lipstick.
Stephanie was notably without her new man, Made In Chelsea star Spencer, despite them being inseparable during the past month or so.
Following the bash, the American reality babe headed off on another solo jaunt for an appearance on Big Brother's Big On The Side.
Once over, Stephanie tweeted: "You guys are THE BEST!!! Thanks for showing me so much UK love!!!!!! Love you all."
