Ben Bader, a beloved influencer, died at the age of 25 on Thursday, October 23.

The Miami-based content creator died 'extremely suddenly' after missing a dinner date, his girlfriend Reem confirmed on social media over the weekend.

Bader had just celebrated his birthday weeks ago on September 22.

She posted an emotional TikTok tribute as she shared the tragic news on Sunday.

'The past few days have been the hardest few days of my entire life and I've never dealt with this before,' she wrote. 'Especially not the loss of someone as important as he was to me.'

She shared that his cause of death is 'still unknown.'

'Ben was the kindest, most caring, most generous person I have ever met in my entire life,' she wrote.

'He genuinely loved every single person that he met and he was so positive all the time,' she continued.

'No one really knows and it seemed to have been extremely sudden,' she said. 'There were really no signs of this happening -- we were supposed to get dinner that night and he seemed so normal.'

She continued: 'I had just talked to him on FaceTime a couple hours before he passed and he was so happy and so normal and he was just smiling and being so funny.'

She gushed about Bader, referring to him as the 'best boyfriend' and said he 'cared so much about her.'

She said she was 'in shock' over his death and also revealed that they had plans to get married and have children together.

About her 'hero' and 'inspiration,' she added: 'I know this is selfish but I just feel like I devoted my everything to him and he devoted his everything to me, only for him to be taken away.

'I feel so lucky to have been loved by him but I'm also so jealous of the people who didn't know him well because it's just so easy to just move on.'
