Those of you who follow the pair on Twitter will already know that Olivia and James are often taking shots at each other on the social media site. Makes sense as they're exes, but more often than not they are actually just joking.
It's just a bit of banter, right?
Olivia had taken to Twitter earlier today, asking fans whether she should keep her hair dark or lighten her locks in time for summer. She tweeted two pictures of herself rocking each look and added the tweet: "Pleaseeee help me! I'm getting my hair done Friday do I go dark or light again??"
Her tweet garnered interest from a handful of her co-stars. Naomi Hedman told her to go light, while Ashleigh Defty insisted Olivia should keep her current raven hue.
James, meanwhile, had another suggestion - cover her face completely. He replied: "@oliviachristina Id grow a long fringe past your chin..."
Olivia then hit back: "You should take your own advice."
Ex On The Beach fans will remember James and Olivia definitely didn't see eye-to-eye on the show. They previously dated for three years and had even been living together, before James decided he was "bored of her."
As you can imagine, things were tense between them when James arrived at the villa and he often came under fire for the way he spoke to Olivia. She struggled to live with him, especially as he struck up a romance with Ashleigh in front of her.
James and Ashleigh had made things official between them out in Portugal, but it never worked out. Ashleigh has since said she regrets getting together with her co-star.
Since the show, though, James and Olivia's relationship has improved. So much so, that the duo were actually forced to deny rumours they had got back together. Fans noticed they had been regularly tweeting each other and had enjoyed several nights out together.
James said at the time: "We were just on a joint PA guys. Not back together! I don't go backwards I go forward."
Olivia added: "Me and James are NOT together and never will be! That chapter is totally done, I have never met a NASTIER piece of s**t in my life."
They did, however, admit they have a love/hate relationship. James had tweeted Olivia to say he missed her as an April Fools' joke. He later added: "Honestly I miss you like so much! Like a f**king hole in the head #aprilfools bitch."
Not surprisingly, it had a lot of people confused and clearing up where he and Olivia stand, James revealed: "We always get on because we know we have both been c**ts to each other! So it's mutual #lovehate."
Right. We think we've got it?
