Miley Cyrus, Kellan Lutz kissing session in Las Vegas, Miley Loves being single

Miley Cyrus is loosely using the term dating when it comes to new love interest, Kellan Lutz because she's too busy and loves being single.

According to E! News, the "Wrecking Ball" singer is enjoying her brief romance with Kellan and was spotted giving a little mouth-to-mouth to each other in Las Vegas after the Britney Spears concert .

"They were making out and didn't seem to care who was watching." The source said, "It wasn't a secret that they were together. She kept grabbing him throughout the night, pulling him with her as she went to leave the venue around 3:30 a.m. You can tell he was into her."

MStars News previously reported:

Miley Cyrus doesn't trust Kellan Lutz during their hookups and believes he's using her now that she's on top of her game. According to Hollywoodlife, sources close to the 21-year-old claim that the pop star doesn't think the relationship is genuine.

 "The timing of these hookups are suspect to Miley," sources say, "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."

Recently, Us Weekly, reported that the alleged couple were getting more serious after their Christmas trip to the Bahamas and plan on spending New Year's Eve together.

"Miley wants Kellan to be her guest at Dick Clark's Rockin' New Year's Eve Concert in New York. Miley is super excited to perform and she's going to be doing something very exciting for the show. Something she's never done before and wants Kellan to be her VIP guest. There's a huge party after the concert as well," the source said.
