J-Law and Nicholas Hoult spotted having a blazing row in public

We've secretly had our hearts set on a Jen-and-Nick reunion since the former couple began work together on the latest X-Men instalment, but it seems it's time to put that dream to rest.

Jennifer and Nicholas, who dated for almost three years before splitting in 2014, had a dinner date last week that ended in disaster, according to one eyewitness. The pair were spotted getting some food together after their appearance at Comic Con, but the low-key meal soon turned into an all out argument.

"Jen was clearly upset with the topic of conversation," the source told Star magazine. "She angrily threw her hands up in the air as she yelled at Nick. Next thing you know, he starts screaming too. It was quite a heated argument."

Hunger Games star Jennifer reportedly walked out on her ex, leaving him alone in the San Diego eatery. Awks.

The tense situation has no doubt been made all the more stressful considering J-Law and Nicholas have to spend huge amounts of time together on the set of X-Men in Montreal, Canada.

The upcoming X-Men: Apocalpyse, which Jennifer has confirmed will be her last film for the franchise, focuses a lot on the relationship between the former couple's characters, Mystique and Beast.

Reports earlier this year suggested that a lovestruck Nick was "determined" to win his ex back during filming, but it doesn't look like things have gone to plan. With Jennifer still rumoured to be dating Coldplay frontman Chris Martin, Nicholas might need to look elsewhere for love…
