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.

"There is not truth [to the report,"] the source told HL. "This report is a totally fabricated story and there is no truth to it whatsoever." 

US reported that Chris Hemsworth's little brother hooked up with the blonde starlet at the Chateau Marmont on Feb. 23. The two were supposedly all over each other and photographed leaving together.

The report also claimed that Hemsworth and Jones bonded over Cyrus' raunchy new image. The "X-Men" star supposedly comforted Hemsworth after he complainted his once-sweet faced fiance had become a wild child.

And Jones and the "Hunger Games" star have not stopped their rumored affair. Hemsworth reportedly sent a sexy, flirty text to Jones this summer that said, "I want to f*** you."

But despite rampant rumors and speculation about Cyrus also being unfaithful, the couple are still together, the source told US.

"Liam and Miley haven't officially split," the source said to the magazine, reported HL. "It's just that neither wants to pull the trigger."
