Jenn Tran has slammed Devin Strader after he ended their engagement over the phone, a day after he got down on one knee.

The Season 21 star of “Bachelorette” criticized her ex’s behavior on social media after Tuesday’s season episode aired.

“What I can’t understand is everything you’ve done since we broke off our engagement,” the 26-year-old said during the After the Final Rose special.

“I end the engagement over a phone call and the next day I wake up and you see girls following me on Instagram — not just any girl, but Maria (Georgas),” she continued, referring to the Season 28 “Bachelor” contestant.

“Not only is that so disrespectful to everything we’ve shared together, I just don’t get it. Why would you do something like that?” Tran asked, claiming his actions made their romance “completely invalid.”

Strader, 28, responded: “I obviously disappointed you. And I can’t say anything else about it. But everything I felt for you was real.”

He didn’t respond to her comment about Georgas, but did respond when she confronted him about going out with co-star Jeremy Simon after they broke up.

“Am I not allowed to live my life?” asked the owner of the freight company. “When we left the show, I had a lot of doubts and to my regret and sorrow, I suppressed those feelings and I told you honestly about it.”

Strader broke off relations with Tran after a 15-minute phone call and allegedly “ghosted” her.

The day before, he had proposed to her with an oval-cut diamond ring, which the former couple could see live on television.

When Tran criticized him on Tuesday for taking that next step despite not being “ready to fight for love,” Strader admitted he “fell short.”

Bachelor Nation member Ashley Iaconetti previously spoke to Page Six and predicted that Trann was not happily engaged.

“I don’t think she’s going to end up with anyone,” the 36-year-old “Bachelor in Paradise” alum said earlier this month.

She explained, “I just don’t know if there’s a connection that I see that stands out above all the others right now.”

“The Bachelorette” is available to stream on Hulu.
