Harry Potter star Evanna Lynch had nine-year relationship with co-star after meeting him on set

Evanna Lynch wasn't always in the thick of the action in the Harry Potter films, which explains how she was able to find time to fall head over heels on set.

The Irish actor, 32, really put the 'love' in Luna Lovegood and struck up a nine-year relationship with one of her co-stars after they met while filming the legendary movie franchise.

Here's a reminder of her introduction:

She burst onto the scene back in 2007 when she joined the star-studded cast for Harry Potter and the Order of the Phoenix as Hogwarts' very own Dolly Daydream.

The fifth instalment of the films centred around the wizarding world was a bit of a turning point in many ways - Sirius Black is killed by his cousin Bellatrix Lestrange, Dolores Umbridge is sentenced to life imprisonment in Azkaban and Harry has survived his second encounter with Lord Voldemort.

Among all that madness, the Boy Who Lived takes serious solace in his quirky new classmate Luna and they bond while going to visit Thestrals - the magical creatures which you can only see after witnessing death.

In between filming these moving scenes, Lynch was also busy eyeing up another actor on set - Robbie Jarvis.

He had a memorable but brief role in Harry Potter and the Order of the Phoenix portraying Harry's father, James Potter, in his teen years while he was a student at Hogwarts in a series of flashbacks.

In the short scene, Jarvis' character can be seen laughing as he uses a spell to disarm a young Severus Snape.

He must have picked up some of the magic that was flying about during filming for the fifth film, as the actor managed to put Lynch under his spell and kicked off what would be a nine-year relationship with her.

They formed a close bond on set and somehow managed to keep their romance under wraps until 2015, when the couple shared the news with fans by uploading a series of Instagram posts confirming their relationship.

Lynch shared a birthday message to her beau on social media in May that year where she referred to him as a 'little babe' and the 'sweetest boy', before saying they were heading to a show together.

They also shared snaps of a trip to Hobbiton in New Zealand, where the Lord of the Rings movies were filmed, which is also the place where the actor managed to convince her other half to go vegan after they were surrounded by free-roaming sheep.

Sadly, Lynch and Jarvis called time on their relationship in 2016, but both insisted that they still remained 'good friends'.

At the premiere of Fantastic Beasts and Where To Find Them, she said: "We're both vegans, so we go to a lot of vegan events together. So yeah, we're good friends."

They even host a vegan podcast together now titled ChickPeeps... so they truly are good pals with the same palette.

But it does beg the question - when are the cast members going to take one for the team and start pumping out Harry Potter babies please? I'm asking for a friend...
