Evanna Lynch admitted to having secret nine-year relationship with her Harry Potter co-star

Harry Potter star Evanna Lynch was in a nine-year relationship with another actor from the films, though kept things under wraps for most of their time together.

Audiences will remember Lynch for her role as Luna Lovegood, the eccentric Ravenclaw witch who was rarely seen without a copy of the Quibbler magazine and liked talking about Nargles.

She joined the hugely popular series in the fifth movie and soon became one of the most popular characters among fans of the franchise.

During that time, she ended up in a relationship with an actor playing another Hogwarts student, though while they got together in 2007, they didn't go public about it until 2015 when she posted pictures of them together to Instagram.

Lynch's pictures showed her visiting New Zealand's Lord of the Rings Hobbiton attraction with Robbie Jarvis, who had also appeared in Harry Potter and the Order of the Phoenix.

However, if you're wondering whether there's any pictures of them on screen together in the Harry Potter films, the answer is no.

Lynch and Jarvis didn't share any scenes together during the making of the Harry Potter movies as he was only in Order of the Phoenix where he played a young James Potter during his school days.

During lessons with Professor Snape (the late, great Alan Rickman) where Harry is attempting to learn Occlumency, the art of how to guard his mind against the invasive magic of Legilimency, he bounces the mind-reading spell back on Snape and gets a glimpse of his father's bullying during school days.

In the memories, James Potter is shown disarming and levitating Snape while threatening to take off his trousers before the potions master kicks Harry out of his mind and brings the lessons to an end.

While he gave audiences a look at what Harry's father looked like when he was younger, by Luna Lovegood showed up James was extremely dead, having been killed by Lord Voldemort (normally Ralph Fiennes, but Richard Bremmer in Philosopher's Stone) long ago.

In James Potter's appearances in other Harry Potter films where Harry's dad appears as an adult (or at least the ghost of one), the role was played by Adrian Rawlins.

Shortly after the announcement of their relationship, the couple amicably split up, with their separation coming in 2016.

However, they appear to have parted on good terms as since their break-up, Lynch said they were still 'good friends' and went to vegan events together.

Lynch is a vegan and Jarvis had previously said that the couple's trip to New Zealand was the last time he ate meat.
