Sarah Harding and Chad Johnson's relationship is reportedly "on the rocks."
The couple struck up a romance while inside the "Celebrity Big Brother" house in August and, although they vowed to make things work in the outside world, it seems the distance between them is putting extra pressure on them because the hunk - who is from Los Angeles - is busy in the US and the blonde singer is still working in the UK.
A source told The Sun Online: "Things are hard - they're so far apart, and there's the time difference too. When they do speak things are tense. It's really tough. Things are really up and down and everyone's saying they're on the rocks."
Tongues were set wagging recently when "The Bachelorette" star, 29, deleted all traces of his partner - including every picture of her and them - from his Instagram account.
But, although they haven't commented or liked one another's pictures in weeks, they do still follow each other and friends have confirmed they're still together at the moment.
And it's believed Sarah, 35, is planning to jet across the pond soon as she has reportedly been inundated with television offers from American bosses
She said recently of their relationship: "It's OK, he's gone back to LA now.
"I've got some work lined up in LA so I'm hoping to go out there in the next few weeks. We spent a week together outside of the house, I'm still acclimatising, we're taking it one bit at a time. We're being sensible."
But the pop star is still trying to get her around her on-screen romance because she never expected to fall for someone when she first went into the house.
She explained: "I wasn't looking for anything when I was in there. I didn't fancy any of the lads when I got in there at all. I didn't look at any of them like that.
"But with me and Chad I think we only had each other to lean on and from becoming really good friends it just grew into feelings when we both got nominated and we both got saved. I think that's when it sort of fell into more feelings."
