The couple – who surprised fans by getting together while competing on The Jump – have struggled to keep up a long-distance relationship, according to the Sun.
A source said: “Stacey found it hard being away from Steve-O so they decided to put their relationship on hold.
“He has a huge tour in the States, as that’s where his fanbase is. The relationship developed quickly and was a real whirlwind, but for the time being it’s not to be.”
Last week we reported that there appeared to be trouble in paradise for the couple as they had failed to share any gushing social media message for some time.
The couple were last seen together at the end of May and at the time Stacey tweeted about hard a long distance romance can be.
She wrote: “It gets harder every time! Hats off to all of you long distance couples making it happen!! See you on the other side @officiallysteveo I miss you already! Lots of love, Stacey.”
The couple initially grew close while taking part in the Channel 4winert sports competition The Jump in February of this year and a month later they went public with their romance.
Speaking about hitting it off, Jackass star Steve-O said: “We were in Austria for six weeks together [for The Jump] and pretty much on the first night I was just getting creepy and looking her up online. I liked her right away and we just started having a great time.”
He also said he doesn’t think they’re that different: “Everyone says that we’re so opposite but I don’t see it.”
Stacey, 25, – who has young sons Leighton and Zachary from previous relationships – admits she had her guard up when they first met and it wasn’t until he was heading back to his native America that she addressed her feelings.
Speaking on ITV’s Lorraine, she added: “I was just attracted to him as a person but the rest of me was just like, ‘No. I’m an independent woman, I’m fine on my own’.
“Then I remember on the last day, I was like, ‘Oh no, he’s going to go home and I might never see him again’, and it went from there really.”
