The identity of the mysterious bachelorette who visits Flajnik during the course of The Bachelor's upcoming season has reportedly been disclosed.

Former fifteenth-season The Bachelor bachelorette Shawntel Newton is the unidentified "lady in red" shown upsetting many of the bachelorettes competing for Flajnik's heart when she visits Flajnik during The Bachelor's recently released season-preview video, RumorFix reported Tuesday.

Newton and Flajnik "were texting and flirting before he started taping [The Bachelor this fall] and she really liked him, so she asked producers if she could go on the show and attempt a relationship with him," a source close to production of the show told RumorFix.

The preview video featured a clip of a brunette calling The Bachelor host Chris Harrison and telling him she was on her way to San Francisco. She was then shown walking into a room wearing a tight-fitted short red dress and heels and later straddling Flajnik in a chair.

The clip also showed the season's bachelorettes discussing how the new girl's arrival posed an unfair threat in the competition and speculating about her connection to The Bachelor star -- as some of them initially believed her to be Flajnik's ex-girlfriend.

"Who is that girl?" Courtney Robertson, a 28-year-old model from Santa Monica, CA, questioned during the video when the mystery girl arrived.

"This f**king stranger walks in...." Rachel Truehart, a 27-year-old fashion sales representative from New York City, NY, said.

"I'm going to kill whoever walks in that door," Emily O'Brien, a 27-year-old PhD student from Chapel Hill, NC, explained.

"What is this girl doing here?" Flajnik asked during the video clip.

"This makes me want to f**king punch a wall," Jaclyn Swartz, a 27-year-old advertising account manager from Newton, MA, said. 

"I'm also here to date Ben," Newton, assuming the RumorFix report is accurate, told the bachelorettes.

"It's just not okay," Nicki Sterling, a 26-year-old dental hygienist from Hurst, TX, expressed in tears.

Former The Bachelor star Brad Womack eliminated Newton, a 25-year-old funeral director from Chico, CA, just after her hometown date -- a decision which determined his final three bachelorettes Ashley Hebert, Chantal O'Brien and Emily Maynard.
