According to the Sun, couple Jessica Wright and Ricky Rayment had an almighty bust up over Ricky's supposed wondering eye.
A source told The Sun: "Ricky entered with Jess on his arm, parading her around before spending the night in the corner with the lads and ignoring her for the rest of the night."
Jess then apparently lost her cool when she noticed that Ricky was checking out other female attendees at the birthday bash.
The source said: "Jess lost the plot when she caught Ricky eyeing up other girls at the do and they had a massive shouting and screaming match with each other."
Jess and Ricky have been dating each other since series five of the show with things getting serious during the last series of the show.
Lucy didn't let the drama ruin her evening however, posing in a party photo booth with boyfriend Mario and tucking into her HUGE birthday cake at the Orsett Hotel, Essex.
Still, a screaming Jessica Wright is probably the last thing Ricky needs to be worrying about right now after reports were released that a Lion from Essex Zoo had escaped.
The 'Essex Lion' has been trending on twitter since its escape.
Fellow Essex resident Proffessor Green took to Twitter last night, poking fun at the cast of TOWIE.
He wrote: "aaaaahahaha there's already an @essex_lion twitter. make yourself useful @essex_lion, find the cast of TOWIE. :)"
