After attending a pre-fight gathering and then watching the big Floyd Mayweather-Saul Alvarez bout in Las Vegas, the now single 23-year-old actor looked to be in a fine mood when he hit nightclub XS with a handful of other guys and a few ladies.
The Catching Fire star may have been on a "guys' weekend in Vegas," as a source told E! News, but he was also seen paying some extra attention to González before the whole group left together at about 2 a.m.
It's unclear just how much of a free agent Hemsworth was when he headed to Vegas, but Miley Cyrus had unfollowed him on Twitter by Saturday and her rep confirmed today that they have ended their 15-month engagement.
Hemsworth returned the favor and unfollowed his ex (he only follows 16 people, it's super easy to keep track) this afternoon.
Coincidentally, Miley is scheduled to be in Vegas this coming Saturday to perform at the iHeartRadio Music Festival.
She'll be singing the record-smashing "Wrecking Ball" live for the first time—and we're going to bet that she makes the most of her leisure hours while she's there, too. Who needs to be 21 when you can twerk?!
