In February, it was rumoured that Liam got 'hot and heavy' with January Jones at a pre-Oscar party.
January was linked to the Hunger Games actor again earlier this month when it was claimed Liam was sending saucy texts to the Mad Men actress. 
According to Us Weekly, he 'fired off a graphic, sexual text message' to January that reportedly said, ‘I want to F**k you.'

Although Liam denied the story, it’s been claimed he is looking for a way out of the relationship. 
A source told Us Weekly, ‘They're just weeks away from calling it off permanently. Liam feels very distant emotionally from Miley these days.
The couple were last seen walking the red carpet as a couple in early August , when Miley supported Liam at the premiere of his new Paranoia in Los Angeles. 
However, witnesses revealed they ‘acted like strangers’. 
‘Miley and Liam acted like they didn't even know each other the entire night,’ a source said. ‘She was wearing her ring but they acted as if they were strangers.
‘[Their kisses] were awkward and he didn't seem into them.’
