Liam Hemsworth Cheated on Miley Cyrus with January Jones

Liam Hemsworth and Miley Cyrus have been engaged since last summer but, according to a new report, they might have just put whatever wedding plans they had on hold, after he spent the night with actress January Jones.

At one of the many parties held last weekend in Hollywood on the occasion of the Oscars 2013, photographers snapped Liam leaving with January Jones, together in the back of the same car.

This could have been just a case of two friends hitching a ride together, but Star is saying in its latest print issue that, in this particular situation, there’s more to it than it appears.

Liam cheated on Miley with January, the tab writes, as cited by Radar Online, Star’s sister publication.

“Liam, who showed up at the swanky soiree at the famed Chateau Marmont hotel without his bride-to-be, had guests aghast as he cozied up to the scandalous single mother, according to Star,” Radar reports.

According to an unnamed insider, the two did more than just “cozy up,” as if there was no one there to see them.

“It looked like they had some hot chemistry. They were all over each other – and they even kissed!” says the spy.

“Meanwhile, Miley, who has been gushing about her relationship with the Hunger Games star in several recent interviews, even referring to him as her ‘hubby,’ hit up the Elton John AIDS Foundation bash on Sunday night solo, where she was ‘all over the place,’ a source tells Star,” Radar further notes.

Perhaps even more telling is the fact that Miley has not been active on her Twitter since February 25, which is when the first pics of Liam and January emerged online, celebrity bloggers note.

However, since this is Star we’re talking about, it’s perhaps advisable to take all of the above with a grain of salt.
