Kellan Lutz is "happily single."
The Hercules 3D star denies he is dating Miley Cyrus—whom he has recently been spotted kissing in both Miami and Las Vegas—claiming they are just really good friends.
He told radio host Ryan Seacrest: "Are we dating? No. It just makes me laugh. I've been friends with Miley for six years. She's a great girl... We are friends and we run in the same circle."
Kellan, 28, also called Miley, 21, a "cool secure woman" and said he doesn't want to be in a relationship at the moment.
He added: "I'm happily single... I'm not [looking for a relationship] right now.
"I'm enjoying life and traveling quite a bit... there's no real time to find the one."
However, a source claims although Kellan and Miley are "just enjoying themselves" with their flirty behaviour, they have a "great chemistry."
The insider told E! news: "They are both spontaneous, fun people, so their personalities match.
"They are having fun together. They have very similar outlooks.
"I am not sure if it has a future, but they have great chemistry, so for the time being they are just having fun."
