DeMario Jackson is firing back at The Bachelorette star Rachel Lindsay after she posted a cryptic tweet about having disloyal friends from the franchise.

Rachel took to Twitter on Friday, writing, "These Bachelor friendships are fickle and fleeting," adding the hashtag "loyalty" to her post, which prompted speculation she was referring to girls on Bachelor in Paradise whom she had befriended while filming Nick Viall's The Bachelor season.

Rachel is rumored to be upset with her friends for partying and spending time with her controversial ex, DeMario, who had an alleged girlfriend back home when dating Rachel on The Bachelorette and also called her out for only being "attracted to white men" when she was notably the first African-American star of the ABC series.

DeMario then shared a Sunday Instagram photo of himself with two fellow bachelors, Dean Unglert and Adam Gottschalk, as they hit up Avenue Los Angeles -- the same club where Raven Gates and Kristina Schulman posted photos of themselves partying.

(Whitney Fransway and Alexis Waters were also part of the crew, but Rachel flat out told Wells Adams on Twitter that she was not talking about Alexis).

In the photo's caption, DeMario addressed an unidentified "someone," but all signs pointed to Rachel.

"Someone said, 'These bachelor friendships are fickle and fleeting' and I disagree," wrote DeMario. "These bachelor friendships got me through a dark time and I'm grateful for my brothers, sisters, and bachelor nation."

DeMario was alluding to his Bachelor in Paradise castmates, who supported him during this summer's sex scandal in which he was accused of taking advantage of Corinne Olympios when she was intoxicated on Day 1 of filming Bachelor in Paradise's fourth season.

Raven and Jasmine Goode, especially, rushed to DeMario's defense and declared him innocent.

DeMario added in his Instagram post, "Hopefully that someone will find real love in paradise next year and stop being petty on social networks. #RoseBoys #Brothers #Blonde #ImBeingPettyNow #TodayIGotTime #TYBG #HiMom."

The second half of DeMario's caption suggests Rachel's engagement to The Bachelorette's thirteenth-season winner, Bryan Abasolo, will not last.

The finale on which Bryan proposed marriage just aired in August, so DeMario seems to think their relationship will fail within a year and Rachel will search for love again in Mexico on Paradise.

Rachel and DeMario's apparent exchange on social media inspired many fans to comment.

Some followers called DeMario petty, asking him to leave Rachel's relationship with Bryan alone.

"Yup! Confused me how her 'squad' still hung out with DeMario after the things he said against Rach," wrote one Twitter user.

Others argued Rachel was just looking for attention and The Bachelor/ette engagements are equally as fleeting as friendships from the franchise.

Back in August when DeMario told The E&G Podcast that he predicted from the start of The Bachelorette season that Rachel would have "a black representative" in her Final 4 for the purpose of being politically correct, Rachel commented on the podcast's Instagram page, "DeMario never knew me and still doesn't."
