“The Amazing Spider-Man” actor Chris Zylka has ended his engagement to model Hanna Beth. The 29-year-old made the details of their split public after going on a nasty Twitter rant. Zylka began his social media melee by revealing that Hanna Beth allegedly cheated on him. He followed that tweet saying the alleged mystery boyfriend was a “guy from boy London” who came bearing “pink flowers.”

Hanna Beth (whose full name is Hanna Beth Merjos) also addressed the breakup on Twitter, though she wasn’t as direct as Zylka. Rather than stoop to his level, Hanna kept things light. The model did not address the cheating allegations or her former fiancé’s attacks on her character in her tweet.

Unfortunately even with her subtlety, Hanna wasn’t spared Zylka’s wrath. The actor replied to her tweet saying, “The truth has been revealed for a long time. Google yourself.” He then replied to a tweet she posted about a night out with friends, calling her a “groupie” and mocking her sobriety.

Zylka then moved on to Instagram. He uploaded a photo of a quote alongside a telling caption that read:

“I’m disappointed that I didn’t see how fake you were, or pay attention to the backstabbing you did in front of me. I will rise up.”

Zylka and Hanna Beth began dating in December 2013. After four months together, the two became engaged. She shared the news via Twitter at the time, writing, “I’m engaged!!!!!” The engagement lasted nearly 10 months.

Before ending his online attack, Zylka assured fans, “All the things I’ve said tonight are things that I looked over and gave my everything to.” He later deleted the message.

This isn’t the first time one of Zylka’s breakups has spilled out onto social media. After calling things off with “Pretty Little Liars” actress Lucy Hale in 2012, Zylka took to the social network to let his followers know it was over.

After a fan tweeted to the “Leftovers” actor about how “gorgeous and sorta perfect” his then-girlfriend was, Zylka replied, “Don’t have a girlfriend. She decided she was too good.” With the exception of one tweet that was quickly deleted, he did not speak of the breakup again and apologized  to fans for his actions.
