Ruby Rose has split from her girlfriend Jess Origliasso.

The 'Orange Is The New Black' actress rekindled her romance with The Veronicas singer while filming the band's music video for 'On Your Side' two years ago, but she has now revealed that they broke up ''a few months ago''.

Taking to social media, she wrote on Twitter: ''I've shared the past two years learning and sharing my life with an amazing human being.

''An experience for which I am very blessed. Breakups are always incredibly hard on the people involved but I can only be grateful for the experiences we shared.

''It's with a heavy heart to share that Jess and I parted ways a few months ago. We still love each other very much and I will always support her and be her biggest advocate.''

Although the post came on April 1 - a date which typically sees people pull pranks - she insisted this wasn't the kind of thing she would joke about.

She added: ''I understand it's 'April 1st' but I would never use something so personal as an April Fool's joke.''

Ruby, 32, and Jess, 33, first started dating the Veronicas musician a decade ago in 2008 before parting ways, and then rekindled their romance in October 2016.

Just last month, they took to social media to gush over their 10 years of memories together.

In a video which was shared on the Instagram story of both Ruby and Jessica, the singer asked her partner: ''What's the best thing about knowing me for 10 years?''

To which Ruby replied: ''Knowing you for 10 years.''

Jessica, who thought she was simply clarifying the question, then proceeded to ask for an answer, to which Ruby sweetly replied: ''No, that is the answer.''

On the 'In My Blood' hitmaker's story, a picture of the pair from 2008 was also shared, as well as a snap of a heart-shaped balloon which read ''Love You'' and was completed with a picture of the pair stuck to it.
