The 29-year-old's previous lovers include a lamp, a transformer truck and even a Halloween figurine.
But the relationships didn't last as Joey's attention waned.
He began dating RoboTroll in December 2017 after feeling 'nostalgic' and rekindled his love for the BattleTrollz collection online.
Smitten Joey, from Taneytown, Maryland, US, was aged 10 when he realised he was objectum meaning attracted to objects.
Now, the performer is looking forward to the future with his beau - including a trip to Florida and potentially a wedding one day.
Joey said: "I realised I was drawn to objects when I was 10 years old, as I wanted to become friends with a lamp at school and would about my day to it.
"But the teacher found out about our relationship and took the lamp away, and I was distraught.
"Over the next few years I fell in love with an animatronic called 'Donna the Dead' and also with the transformer Optimus Prime when he was in truck form.
