Things are not boding well for Jordan Rodgers after the final rose.

Though the former professional football player and Bachelorette JoJo Fletcher got engaged on the season 12 finale of the ABC reality series, the athlete is at the center of an alleged cheating scandal nearly three weeks after it was revealed that the duo are preparing to say “I do.”

On Thursday evening, Rodgers’ ex-girlfriend Brittany Farrar made allegations in a series of two (now deleted) Instagram posts that the athlete was unfaithful to her in 2014.

Clues within the video point onlookers to believe that Rodgers had a relationship with a cast member (Kelley Jakle) from Pitch Perfect 2, in which the 27-year-old made a cameo appearance alongside members of the Green Bay Packers. In the 2015 release, Rodgers can be seen dancing next to the NFL stars who sing an acapella version of Destiny’s Child’s “Bootlylicious.”

In Farrar’s second Instagram post which has since been deleted, she shared a video slideshow that included a receipt for flowers that Rodgers allegedly purchased for another woman.

The alleged message that was included with the flower purchase read, “Happy Birthday To My Favorite Bella. Miss You. Can’t Wait To See That Beautiful Smile Again. From, Your Favorite Football Player Wanna Be Actor.”

Though Farrar did not name the woman she believes her ex-beau allegedly cheated with, the receipt includes information that points to a specific Barden Bella.

In the video, the image of the receipt reads that a purchase was made by Jordan Rodgers for “Cut Flower Arrgmnt in Vase” with the notes “Mix with roses !!! Big, beautiful and colorful in a nice vase!” on Friday, June 27, 2014, with a billing address of “Chico, CA 95973” – Rodgers’ hometown.

Despite the recipient’s first and last name and delivery address being blurred out, the first initial of the first name – K – and city and state – Baton Rouge, LA – were intentionally left unmarked.

Jakle, who starred in Pitch Perfect and Pitch Perfect 2 – both of which were filmed in Baton Rouge – as Jessica, was born on June 27, Hollywood Life first reported.

The actress, who is from Sacramento, California, coincidentally grew up an estimated hour-and-a-half south from Rodgers’ hometown of Chico.

Rodgers and Jakle also have ties to the weight loss management brand MetPro. In an infomercial published July 27 on YouTube that lists Jakle and fellow Barden Bella Brittany Snow as two of its users, Rodgers explains why both celebrities and athletes use the product. “Celebrities like Kelley Jakle and Brittany Snow use MetPro to be ready for anything their job requires,” the video description reads.

In his recent exclusive PEOPLE cover interview with his fiancée Fletcher, Rodgers said the rumors that plagued him throughout the season were “awful.”

On Friday, Farrar took to Instagram again to address the allegations, and claimed of the deleted posts, “Somebody doesn’t want this info out there and keeps taking down the posts.”

“Somebody doesn’t want this info out there and keeps taking down the posts. You can delete my posts but you can’t erase the truth,” she captioned a video with the hashtags, “#ButCanIKeepTheHashtags?

A rep for Jakle did not immediately respond to PEOPLE’s request for comment.
