It's no secret that the singer has a wild side, which was rumoured to be the reason for their initial four-year split in 2013.
'It’s obvious that she’s even more comfortable letting her hair down when her husband is not around,' the insider told Life & Style.
The ex-Disney star's hit song "Wrecking Ball" was released shortly after the celebrity couple's first break-up six years ago.
Fans believe the song was about the Hunger Games actor, and Miley's impassioned words before performing the track at Glastonbury have added to pre-existing concerns about the strength of their relationship.
However, Miley put the rumours to bed after commenting on a fan's Instagram post this week which questioned the status of Miley's and Liam's relationship.
"Miley sang the song 'Wrecking Ball' and she said, 'I'm fucking sick of men,' I hope Miley and Liam's relationship still going good but I'm not sure," wrote the concerned fan.
"It was politically directed," the Hannah Montana star reassured the fan in her response.
Fans were relieved to hear this, as many of them have been following Miley and Liam's relationship since they were co-stars in the film The Last Song.
Earlier this month, the Wrecking Ball singer tweeted a sweet picture of their first kiss while onset of The Last Song in 2009.
‘Started digging you in 2009, Sh**t got deep’ wrote Miley, adding an engagement ring emoji.
Miley and Liam got married in a secret ceremony at their home on Christmas Eve last year.
