Season 12 of the hit ABC show premiered on Monday
, and contestant Jordan Rodgers -- whose brother is Green Bay Packers quarterback Aaron Rodgers
-- has already found himself embroiled in a cheating scandal. On the premiere episode, the handsome 27-year-old former NFL player had some clear chemistry with this season's star, JoJo Fletcher, and has emerged as a clear frontrunner after they shared a steamy smooch.
Though we know one person far from jazzed about Jordan's appearance on The Bachelorette -- trainer Brittany Farrar, who claims to be his ex-girlfriend. Brittany slammed Jordan on Instagram on Monday, accusing him of cheating and wanting to be on the show to be famous. Brittany tagged both Jordan and the ABC show's official Instagram in the shade-filled post, and also took a dig at Jordan's Pitch Perfect 2 cameo.
"Riding the bench doesn't get in the way of a relationship, but cheating does. #yourpitchisntperfect @jrodgers11 #alwayswantedtobefamous #dreamscometrue #tuneinnextweekformoreBS," Brittany captioned a video featuring Chris Pratt doing a humorous "Oh, snap" face.
To add to the drama, Brittany appears to be close friends with Aaron's girlfriend
, actress Olivia Munn. Just last week, the X-Men: Apocalypse
actress Instagrammed a pic of the two with her and Aaron's dogs, Frankie and Chance.
"@frankierodgers12 wiped out after his first @brittany.farrar workout. I feel ya buddy. She kicks my butt, too," Olivia wrote.
Brittany also attended the Ride Along 2 premiere in January in Miami Beach, Florida, to support Olivia.
"Supporting my stunning, brilliant friend at her premiere of #ridealong2 last night was everything," she Instagrammed
"Premiere night with this fox couldn't have been more fun," she added in another post of the two together.
Meanwhile, Jordan hasn't commented on Brittany, and seems to be focused on winning JoJo's heart.
"I'd say night one is headed in the right direction... #bachelorette #firstkiss," he captioned an Instagram pic of him and JoJo cuddling on Monday.
"I would just want someone who is genuine and makes me laugh, and is my best friend and ultimately someone who is going to love me as much as I love them," she told ET exclusively.
