The pop star and the actor were spotted together at the opening of Beacher's Madhouse in Las Vegas on Friday, Dec. 27., sparking rumors—again—that they might be more than friends.
The "Adore You" singer, who attended Britney Spears' Piece of Me show before heading to the bash shortly after midnight, was clad in a nude longsleeve crop top and a black mini-skirt with suspenders. The Twilight heartthrob, who arrived just before 2 a.m., sported a black leather jacket and a matching baseball cap for the night out.
Cyrus seemed to be enjoying her evening with a bunch of partygoers, and was photographed dancing with Katy Perry.
According to an eyewitness at the party, the 21-year-old crooner kept pulling the 28-year-old hunk into her and putting her arms around his neck. Lutz, who seemed a little bit shy from the attention they were receiving, watched Cyrus as she danced on top of the banquette. They left together at around 3:30 a.m.
Reports began swirling that Cyrus and Lutz were an item after they were seen arriving in Miami on the same private jet on Wednesday, Dec. 18.
Despite the dating speculation surrounding the attractive duo, a source told E! News at the time they are "definitely not a couple."
Lutz flatly denied the claims shortly after the sighting as he signed autographs for fans at LAX after flying home from Miami on Thursday, Dec. 19.
"You guys are stupid," he said, smiling, in an exchange caught on video by X17online.
So he's not dating Miley, then?
"No, I'm happily single," the 28-year-old Twilight heartthrob replied. "I am very focused on work."
