You can't mess with true love -- at least, that's what JoJo Fletcher and Jordan Rodgers are proving!

The adorable duo, who got engaged during the season 12 finale of The Bachelorette, are still going strong, amid recent drama with Rodgers' ex-girlfriend, Brittany Farrar, who claims the former NFL pro cheated on her with a woman he met while filming a scene in Pitch Perfect 2.

Fletcher took to Instagram on Saturday to show off her engagement ring, while letting the world know that she and her beau are very much still in love and are paying no mind to the haters.

"The best thing to hold onto in life is each other.... & tacos," the 25-year-old brunette beauty captioned the cute pic of the two holding hands.

A few hours later, Rodgers, 27, shared a snap to his own account, echoing his fiancée's sweet sentiments in the caption.

"Always holding on to my best friend...but where are these tacos you speak of @joelle_fletcher?" he wrote. "I can multi-task..."

The posts come just one day after Farrar slammed Rodgers over Instagram, showing receipts from a flower order the 27-year-old reality star allegedly made and sent to "the girl he cheated on me with in Louisiana."

As ET previously reported, the message that appears on the receipt, which was to be delivered with the flowers, appears to read, "Happy Birthday to my Favorite Bella. Miss you. Can't Wait to To See That Beautiful Smile Again. From, Your Favorite Football Player Wanna Be Actor."

In another post, Farrar shared a lengthy open letter about Rodgers calling her a liar. Hear more on how the high-profile feud between the two began in the video below.
