Round two!

After their explosive fight aired during last week’s episode of Teen Mom 2, Kailyn Lowry and Javi Marroquin have been continuing to feud on Twitter — and their latest spat is about the real reason for their divorce.

Kailyn, 24, made an appearance with her co-star Leah Messer on last night’s live Teen Mom 2 aftershow where the girls discussed their storylines this season. But the drama started when Kailyn answered a fan’s question about whether she would ever get married again or have more kids. She answered no to marriage, but yes to kids — and Javi quickly pounced on Twitter with his reaction.

No less than one minute later, Kailyn clapped back at Javi’s shade.

“You blamed me for miscarrying and our marriage was toxic, Why would I want more kids with you?” she asked.

Even though Kail deleted her tweet two hours later, it still lives on in screenshots and Javi chose not to respond.

“Just deleted my response. Not worth it. Tweets back and forth solve nothing,” she wrote.

Kailyn and Javi were married for four years before they announced their split last spring, and they finalized their divorce last December. Javi and Kail share three-year-old son Lincoln together, and Javi also helped raise Kailyn's seven-year-old son Isaac — whom she shares with her ex-boyfriend, Jo Rivera.
