A day after Kellan Lutz arrived in Miami on the same private plane as Miley Cyrus, people wanted to know if he and the 21-year-old Wrecking Ball singer were dating.

However, the question somewhat annoyed the former Twilight star.

"You guys are stupid," Lutz said, smiling, as he signed autographs for fans at LAX on Wednesday, Dec. 18, after flying home from Miami, an exchange caught on video by X17online"No, I'm happily single. I am very focused on work."

When asked if they are hooking up, Lutz replied, "You can write all the rumors you want, I really don't care." 

Lutz, 28, will be seen on the big screen next playing the title role in Hercules: The Legend Begins. The film's trailer shows that the actor has been working hard to also get buff for the role as the son of a Greek god.

Cyrus has also been focusing on her music as of late. She traveled the country recently performing at various Jingle Balls and she tweeted Wednesday, Dec. 18, that the video for Adore You, the next single off of Bangerz, is coming soon. Cyrus kicks off her Bangerz tour on Feb. 14 in Vancouver and end April 24 at Nassau Coliseum on Long Island, N.Y. Icona Pop and Sky Ferreira will headline the 38-day arena tour. 

Lutz and Cyrus were photographed stepped off the same private plane in The Sunshine State on Wednesday. Lutz wore a beanie and dark shades, dark jeans, flip-flops and a striped shirt. The singer wore denim shorts, white sweater, gold jewelry and animal print booties.
