Miley Cyrus And Liam Hemsworth Break Up Rumors Shot Down, Actress Smoking – Is She Nervous About January Jones?

Singer Miley Cyrus's engagement was rumored to have been on the rocks after her fiancé Liam Hemsworth was seen partying with model and actress January Jones at the pre-Oscar party at Chateau Marmon, Feb. 23, while Cyrus was busy attending Elton John's annual AIDS Foundation Oscar viewing party.

But sources told E! News that the couple did not break up and are still together contrary to rumors. "They are totally together," the source said.

The source also said that there was no "drama" over Cyrus and Hemsworth going for separate events. Cyrus attended Elton's event without Hemsworth because her mom had never been to his event and wanted to. So the singer took her mom instead.

But Hemsworth was spotted partying with Jones and later left the venue getting into the same car.

"It looked like [Liam and January] had some hot chemistry," a source inside the pre-Oscars party told Star magazine. "Liam got January's coat and helped her put it on, then they headed outside. They made sure to leave a few seconds apart, so they wouldn't attract too much attention. Then they jumped into a waiting car and took off," the source added.

HollywoodLife reported that Cyrus was seen smoking a cigarette near her Los Angeles studio, Feb 27 and was keen to know if she was nervous about the relationship.
