Jordan Rodgers isn't being honest about his past with The Bachelorette viewers and JoJo Fletcher, according to his ex-girlfriend Brittany Farrar.

Jordan, a 27-year-old former pro quarterback from Chico, CA, won the first kiss of the season as well as Fletcher's First Impression Rose during Monday night's premiere of The Bachelorette's twelfth season.

In his intro package, Jordan shared a sob story about how his time-consuming career as a professional athlete resulted in a crumbled relationship with a woman he saw a future with.

"[Football] did pay a toll on what was an important relationship to me at the time. I was in love, but I was so focused on football that I didn't make time for anything else. When that relationship ended, it did hurt really bad. It was my fault. The one woman I was in love with wasn't in love with me anymore. Now I'm in a place where I'm ready to make love a priority," Jordan said in the episode.

However, Jordan's ex-girlfriend is publicly calling him a liar and saying their romance failed because he was unfaithful. She also suggests Jordan is on The Bachelorette for the publicity.

"Riding the bench doesn't get in the way of a relationship, but cheating does. #yourpitchisntperfect @jrodgers11 #alwayswantedtobefamous #dreamscometrue #tuneinnextweekformoreBS @bacheloretteabc," Farrar wrote on Instagram.

Farrar's post on social media prompted shocked responses from fans -- including "shots fired," "NO WAY" and "lmao."

Farrar's "riding the bench" comment is an apparent reference to the fact that while Jordan, the younger brother of Green Bay Packers quarterback Aaron Rodgers, is being billed as a "former pro quarterback," he never actually played in a professional game.

After going undrafted in the 2013 NFL Draft, Jordan signed as a free agent with the NFL's Jacksonville Jaguars in May 2013 but was released by the Jaguars two months later before they began training camp. He was subsequently out of the NFL for three months before spending the rest of 2013 NFL season on the practice squad of the Tampa Bay Buccaneers. Jordan then tried to catch on with the Miami Dolphins but was cut in May 2014 after spending only five weeks in their offseason program. 

Jordan then attempted to launch a career in Canada's CFL football league with the British Columbia Lions. After being a member of the Lions' practice squad in late 2014, Jordan was set to battle for a roster spot at the team's Spring 2015 training camp, however he suddenly decided to retire to pursue a career in television only days before camp began.

Jordan reportedly made his retirement decision after his brother Aaron landed him a small acting role playing a Green Bay Packers player in the movie Pitch Perfect 2.

"In the offseason he had some chances to do some auditions and it worked out pretty well for him," Lions head coach Jeff Tedford told the Vancouver Sun last May.

"His heart was kind of going in that direction. I admire him. It's hard to say, at 26, that you’re finished with football, as much as he loves it. He understood that, if he's not 100 percent into this, he should be into something else."

Farrar's Instagram also includes recent photos of her spending time and traveling with Hollywood actress Olivia Munn, who is the girlfriend of Aaron, 32. Munn -- who has been dating Aaron since 2014 -- is apparently friends with Farrar and also trains with the Nashville-based personal trainer.
