The Bachelorette's Michael Turnbull is in trouble - again. 

The Bachelorette runner-up Michael Turnbull has come under fire for joking that he and Sam Frost are texting behind her boyfriend Sasha Mielczarek’s back.

Turnbull jokingly made the comments to a Fox Sports’ Shootout presenter – but Frost, 26, was not impressed.

Writing on the Fox Sports Football Facebook page, she posted “Get a grip Turnbull”.

"Excuse me? Whether it's said in jest or not, suggesting I'm sneaking around my partner's back is offensive and disrespectful to both Sasha and myself," she added.

The post and the comments have been deleted, but not before it was screenshotted and published by the Daily Mail.

But it's just the latest tiff between the two.

Last month, Frost told NW magazine that Richie Strahan was her "real runner up", but that she'd chosen Turnbull to spare Strahan's ultimate rejection at the finale.

Turnbull reponded by telling the Daily Mail that he was hurt by her comments.

"It wasn't easy to read, and if that's the truth, she should have let me go... I think she should have let me go as soon as she realised that I was not the guy for her" he said at the time.

Check out Sam and Sasha's interview with The Project. Post continues after video.

Turnbull has also been at the centre of a few different controversies - he was criticised for exaggerating his soccer career in September, and more recently for wearing a fake Rolex watch.

Oh dear...

Look, we're sure there have been some hurt feelings behind the scenes - but it's probably time that both Turnbull AND Frost let it go already...

Do you think Michael was wrong for saying what he did?
