Miley Cyrus and hot Liam Hemsworth are making headlines again. The "Hunger Games" star is allegedly cheating on the "Wrecking Ball" singer. 

According to an US Weekly report, the Vevo record breaker is supposedly with an unfaithful mate, who is sexting "Mad Men" star, January Jones.

Reportedly, the couple's troubles stem from Hemsworth's inability to remain unfaithful and not Cyrus's controversial image and antics. But a source told Hollywood Life exclusively that the report is false.
