It's been nearly a year since Christina and Tarek El Moussa's explosive fight that resulted in the two splitting up, but it appears the Flip or Flop stars are not completely over it.

On Thursday, Tarek posted a photo to his Instagram story of himself posing in front of a sign at BJ's Cabana Bar in Lake Havasu City, Arizona. The sign read, "No guns, weapons of any type." Tarek added text to the snap, writing "or helicopters," tagging his estranged wife and topping it off with a middle finger emoji.

The reality star has since deleted the pic, but judging by what Christina posted to her Instagram on Friday, we imagine she wasn't too happy when she saw it.

The blond beauty shared a photo of the Empire State Building with the quote, "No time for bullshit when you're building an empire."

"True that," she captioned it. Only surround yourself with the best ❤"

But that's not all! Tarek even gave the post a "like."

A source close to Tarek later told TMZ that his post was supposed to be a joke, and he tagged Christina thinking she would find it funny. The middle finger emoji was reportedly directed at the incident, not his co-star.

On Friday, Tarek tried to clear the air with an Instagram post that read, "#life is about having #fun and enjoying every #moment....people shouldn't take things so seriously especially JOKES that are meant to be playful and fun..."

Many of Tarek's fans took to social media to express their support, writing things like, "Reading the comments people leave you makes me realize how many sadly have no sense of humor," "The fact that you're able to joke about your past means that you've already moved on... I admire your personality," and "The only way to get through life is with a little humor!! Keep doing great things!!"

Last December, the couple confirmed they were taking a step back from their marriage following an incident on May, 23 2016 that led to the police being called to their Orange County, California, home. At the time, Tarek allegedly had a handgun and the Sherriff's Department responded to a report of a "suicidal male" with a helicopter.
