Even though Liam is putting on a very positive front publicly as he wished her ‘nothing but health and happiness’ behind closed doors, Life & Style claims it’s a very different matter.
‘It takes a lot to wind up Liam but Miley’s managed to do it,’ adds the source.
According to the insider the main things that triggered him was his wife flaunting her relationship with Kaitlynn Jenner and leaks to the media that he was ‘a drunk and a pill popper.’
‘It’s all been too much,’ the source says, adding Miley’s revenge single has not helped.
Miley meanwhile is said to think ‘it’s unfair that she’s the one getting blamed for he split when Liam is far from perfect.’
While the duo have not yet commented on Life & Style’s allegations of a deterioration of relations, Miley has vehemently denied she cheated on Liam since they reconciled in 2015, following their split in 2013.
'I can accept that the life I’ve chosen means I must live completely open and transparent with my fans who I love, and the public, 100% of the time,’ she tweeted. ‘What I cannot accept is being told I’m lying to cover up a crime I haven’t committed. I have nothing to hide.
‘I f****d up and cheated in relationships when I was young.
‘But the truth is, once Liam & I reconciled, I meant it, & I was committed. There are NO secrets to uncover here. I’ve learned from every experience in my life. I’m not perfect, I don’t want to be, it’s boring. I’ve grown up in front of you, but the bottom line is, I HAVE GROWN UP.
‘I can admit to a lot of things but I refuse to admit that my marriage ended because of cheating. Liam and I have been together for a decade. I’ve said it before & it remains true, I love Liam and always will.’
