Liam Hemsworth may have just gone through a very public breakup, but that didn’t stop him from having some fun over the weekend in Vegas.

The 23-year old “Hunger Games” star was spotted out and about at the Mayweather/Canelo fight on Friday night, hanging out with pals that included “Twilight” star Ashley Greene. A “source’ told E! News that he seemed to be in good spirits and was having a good time.

On Monday, it was officially announced that Hemsworth and fiancee Miley Cyrus have split for good and that it was her decision, reportedly because he was unfaithful to her over the course of their 4-year relationship. Last week rumors made the rounds across the web that Hemsworth had been “sexting” with “Mad Men” star January Jones after the duo were spotted in March getting close at a pre-Oscar party. His rep has denied it.

“The story of Liam Hemsworth and January Jones is entirely fabricated by US Weekly. There is no truth whatsoever to this tabloid fiction,” the rep said.

Cyrus and Hemsworth have had a rocky relationship over the years, breaking up and getting back together several times. Hemsworth was reportedly “embarrassed” by her performance at the MTV VMAs earlier this year and made headlines when he didn’t attend the show.
