Tarek El Moussa wants the last word in a bizarre Instagram feud between him and soon-to-be ex-wife Christina.

The "Flip or Flop" star said it takes a lot to keep him down. "Like life... when you get knocked down you get back up," the 35-year-old wrote on Instagram Sunday seemingly chiming in on the ongoing social media war between him and his ex.

The feud started Thursday after Tarek made a joke about the explosive fight that led to their split and Christina responded.

He posted a pic of himself posing under a sign that read, “No guns, weapons of any type.” The reality star then added the words “or helicopters,” tagged his estranged wife and added a middle finger emoji.

The post which was subsequently deleted, appeared to reference a
combustible fight the couple had in May 2016, when Christina called the police to their home because Tarek had stormed out and she was nervous that he would kill himself.

The police aided by a helicopter eventually found Tarek who said
he had “no intention of hurting himself.” The couple announced their split in December of last year.

On Friday, May 12, Christina, 33 appeared to answer back.

She posted a picture of the Empire State Building emblazoned
with the quote, “No time for bulls--t when you’re building an empire.”

“True that,” she captioned the post. “Only surround yourself with the best.”

Tarek “liked” the post and later that day addressed the skirmish.

“#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… happy Friday!!” he wrote alongside a photo of him surfing.

The couple who are parents of Taylor, 6, and Brayden, 20 months have continued to work together despite their split. They even walked the red carpet together at the Daytime Emmys last month.
