Buttermore was born in 1990 and had celebrated her 36th birthday last month on February 25.

Buttermore continued her studies at the same university and received a PhD in Biomedical Sciences, Pathology & Cell Biology.

Along with Nippard, Buttermore was also a fitness influencer and had 524,000 followers on her Instagram account.

‘I currently do cancer research but LOVE to workout and eat good food!’ she had also written.
‘My channel brings informative content to the world of fitness, training, beauty, lifestyle, food challenges and nutrition all with a scientific twist!!’
Her last video had been uploaded two years earlier and was titled: ‘How I Feel About My New Body.’
Buttermore had also shared fitness posts to Instagram as well as updates on her life to her followers on the social media platform.
Nippard additionally made cameos in photo series that she had uploaded to her main page.
Back in March 2024, she took a break from social media and returned two months later to share what she learned after stepping away.
‘My mental health has been the best it’s ever been,’ she had penned at the time while adding that her anxiety is something that she ‘no longer struggles with.’
‘It was almost crippling a few years ago to the point I felt I couldn’t breathe or leave my house,’ she candidly recalled.

Buttermore admitted that she did ‘miss my social media friends and community’ but is ‘way more present’ without social media.
‘Sometimes I still feel a void in my day-to-day life from being so removed from this app, but the positives from taking this break has been worth it. But believe me when I say I love and miss you, I truly mean it.’
The May 2024 post was also her last upload to Instagram.
In November 2022, Nippard announced that he had proposed to Buttermore and shared the news of their engagement.
He recalled at the time that six years earlier, he ‘slid into her DMs’ and they ‘immediately formed a friendship.’
‘We started Skyping for 3-4 hours every day for about a month (no joke) until I went to visit her in Florida from Canada. Our first date was a shoulder workout and I will never forget it…’
The pair dated while doing long distance as he lived in Canada and she resided in the United States.
‘We grew together as we learned from each other, travelled the world together, always supported each other, and used the power couple equation to build each other up in so many different ways,’ he also wrote.

‘Relationshipmaxxing with tea time to lower cortisol levels ❤️,’ he had penned in the caption.
The pair held big smiles on their faces as Nippard draped one of his arms over Buttermore’s shoulders.
