Miley Cyrus is allegedly suspicious of "Twilight" actor Kellan Lutz's intentions of being seen around her.

According to Hollywood Life, the two stars were spotted at the opening of Beacher's Madhouse on Dec. 27. Cyrus was pictured kissing Lutz on the neck and check while they were out partying together.

"The timing of these hookups are suspect to Miley," a source revealed to HollywoodLife.com. "She thinks that he might be using her for the media aspect of things. He has a movie coming out next week and a lot of late night shows and other places will cover [their relationship], and will want to book him on their shows. So she is very suspect of his true intentions, that is the main reason she isn't diving into a relationship with him."

Cyrus and Lutz have reportedly been hooking up since the beginning of December, but the "Wrecking Ball" singer isn't looking for anything serious.

"Miley was having so much fun at Beacher's," the source said. "Kellan and Miley were talking although she seemed more into being the life of the party. It looked like Miley and Kellan ended up leaving together though."

In a recent interview with Barbara Walters, Cyrus revealed she didn't understand the kind of commitment she was making at 19-years-old, referring to her engagement to "Hunger Games" actor Liam Hemsworth.

"I don't think I realized what 19 truly is, and I got engaged at 19, and I definitely wouldn't change being engaged," Cyrus told Walters. "It was so fun wearing a fat rock for a few years, but now, I just feel like I can actually be happy. I wait for those moments of silence, when I'm just at my house, by myself."

 "I was so scared of ever being alone, and I think, conquering that fear, this year, was actually bigger than any other transition that I had, this entire year," she added.
