They're getting married soon
Miley, 20, and Liam, 22, have recently faced rumours about his flirtacious behaviour – and they did little to quell speculation that things aren’t all rosy when they stepped out in LA together looking a little glum.
Miley also tellingly Tweeted that she was ‘in need of girlfriends’.
Those signs of trouble in paradise came as Miley is busy planning her wedding to Liam.
She told Ellen Degeneres: ‘I didn’t realise how much there was to do until I got a wedding planning book.
‘I don’t care what colour the napkins are. I don’t want to get too caught up in the little moments.’
You know what they say about smoke and fire…
