Liam Hemsworth Flying Solo for Floyd Mayfeather Vs. Canelo Alvarez Las Vegas Fight

Liam Hemsworth was flying solo as he tended the VIP Pre-Fight Party for Showtime PPV's Presentation of The One: Floyd Mayweather Jr. vs Canelo Alvarez in Las Vegas Saturday night, Sept. 14, Us Weekly reported.

The Catching Fire actor showed up alone for the big event at the MGM Grand Garden Arena. Before heading to the MGM Arena, the 23-year-old actor first went to the private Beacher's Madhouse pre-fight cocktail party. He was reportedly having fun and stayed for two hours. He was not talking to any girl in particular. However, a source told Us Weekly that he talked to Heidi Klum for a short time.

The actor looked handsome wearing a comfortable white T-shirt with a light blue open button-up. He smiled for the cameras before heading inside but decided against walking in the red carpet.

His appearance came just hours after his fiancé Miley Cyrus unfollowed him on Twitter. This awkward yet public move might be one of the signs that the end is near for the four year relationships of the couple.

Us Weekly reported that even if the Paranoia actor currently lives at Cyrus's home in Toluca Lake, the two have been drifting apart. They don't even share the same room anymore. A source added that the actor has been wanting to leave for a while now.

"They're just weeks away from calling it off permanently," said the source.
