Jenn Tran pissed off Devin Strader after he broke off their engagement over the phone – one day after he got down on one knee.

The lead actress of “Bachelorette” season 21 criticized her ex’s social media behavior after the finale aired on Tuesday.

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

“I broke off the engagement with a phone call and the next day I wake up and I’m following girls on Instagram – not just any girl, but Maria (Georgas),” she continued, referring to the contestant on season 28 of “The Bachelor.”

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

Strader, 28, replied: “Obviously I disappointed you. And I can’t say anything else. But everything I felt for you was real.”

While he did not respond to her comment about Georgas, he did hit back when she called him out for going clubbing with his co-star Jeremy Simon after their split.

“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 unfortunately and sadly, I suppressed those feelings and I came clean to you.”

Strader broke up with Tran during 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 had to watch live on air.

When Tran reprimanded him on Tuesday for taking the next step despite being “not willing to fight for love,” Strader admitted that he “wasn’t enough.”

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

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

She explained: “I just don’t know if there is a connection that particularly stands out to me at the moment.”

“The Bachelorette” is streaming on Hulu.
