Ellie Harrison partner: Ellie and partner Matt are not married but they have been engaged since 2005.
The Countryfile presenter had scarification on her arm, which included 10 scars in total to represent the years they had been together.
Ellie has previously opened up on why she chose to undergo the scarification to Event magazine.
She told the magazine: “I presented my arm to him in this kind of clingfilm wrap.
“You have to scrub [the cuts] out and put Vaseline on, then clingfilm to keep the wounds open and clean.
Ellie Harrison partner: Ellie has previously opened up on getting scarification done for partner Matt.
“He was a bit shocked, I must say. He said he was conflicted because I’d hurt myself in this pursuit, but he was obviously really quite emotional.”
The Countryfile presenter went on to say while they are not married, this was her “offering” to him.
Ellie continued: “We’re not married, but this was my great offering to him.
“Obviously if he leaves me I’ll have to create a different story about what it’s about!

“He’s the most handsome man on Earth.
“He’s my beloved, and I hope we die together. Not yet. But that’s my wish – that we end up dying together.”
Ellie is seen to keep her life away from Countryfile out of the spotlight and does not have any social media accounts.
The 42-year-old has previously opened up on why she has chosen to stay away from social media.
Ellie Harrison partner: Ellie has also spoken of why she does not go on social media.
Talking to Radio Times in 2017, Ellie said: “I don’t engage with Twitter conversations because I’m frightened it will ruin my day. I prefer not to look at all.”
Last year Ellie also spoke of not having a presence on social media to Express.co.uk.
Ellie explained: “I don’t have Twitter or Instagram and anything that’s programme-specific is dealt with by the producers.
“Unless there’s anything, in particular, I need to be pulled up on, then I tend not to hear about it. And I choose to keep it that way.”
The presenter went on to say how while she had previously been on Twitter, it left her feeling down.
Ellie continued: “I had Twitter until Christmas then I came off everything at the same time thinking this isn’t lifting me up, this isn’t bringing anything warm or good into my life.”
Countryfile airs tonight on BBC One at 4.30pm.
