It may be all fun and games on the set of "Two and a Half Men," but when it comes to kissing his co-star Miley Cyrus in front of her fiancé, Liam Hemsworth, Angus T. Jones says that's a whole other story.

Cyrus, 19, who falls for Jones, also 19, during her two-episode guest appearance on the show, recently said kissing him when she's engaged is "weird" -- and Jones couldn't agree more.

"It was silly," Jones laughed when E! News asked about his smooch scene with Cyrus. "Acting kissing is one of the weirdest things that you have to do."

Especially when your co-star's future husband drops by the set for a quick visit ...

"He came down when we shot on Friday. I said, 'Hey,'" Jones recalled of Hemsworth's visit before joking, "I said, 'Ya know, it's strictly business between me and Miley.' She's definitely his."

However, Angus says Honey Boo Boo child could be the game-changer. "She said she loves watching it," Angus confirmed of Cyrus' love for Alana Thompson, adding, "And tortures her fiancé with it."

As for what the future holds between Jones and Cyrus, the actor admits he'd love it if she'd return for more episodes (her stint ends this Thursday).

"It was a lot of fun," Angus said of working with Cyrus. "She is extremely talented, extremely hilarious and she's an awesome person to have on set."
