Reality TV star Lauren Stoner shows off her toned figure in mis-matched bikini as she celebrates her birthday on Miami Beach

Lauren Stoner's 2010 E! Reality series may not have found success, but the 31-year-old still had plenty of reason to celebrate on Thursday.

And she seemed to be doing just that as she took to Miami Beach with a group of friends in honor of her birthday.

She sported a mismatched bikini for the celebration, which showed off the former TV star's toned figure.

Lauren sported a light blue and pink patterned string bikini top, which was embellished with gold rings.

She coupled that with tiny, navy blue bottoms for a mismatched look during her visit with friends at The Setai Hotel. 

Her long blonde hair was in beachy waves, and she accessorized with small stud earrings, a gold necklace, and a silver watch.

The blonde beauty seemed to be enjoying herself on the vacation, as she was spotted smiling as she sipped on coconut water.

She was also seen lounging on a towel-covered beach chair as she took in some sun on her relaxing, hometown visit.

The former Hollywood PR girl had recently been in London, where she took in the 2014 Victoria's Secret Fashion Show.

Lauren came to the forefront when she starred alongside Kim Kardashian's best friend Jonathon Cheban in E!'s 2010 show The Spin Crowd.

Kim was one of the producers on the show that made its debut in August 2010.

While it was supposed to give an exciting insight into the thrilling world of celebrity PR, the show was cancelled after an embarrassing eight episodes due to dismal ratings.
