Appearing on Thursday's episode of Ashton Kutcher's Two and a Half Men, Miley Cyrus took special care when getting to get into character as Missi, the quirky, chatterbox daughter of one of Walden's (Kutcher) friends.
"I play someone who can't shut up, [and] I had to do a lot of character building," Cyrus joked to Jay Leno during an interview Friday promoting her appearance. "I had to go deep on that."
As the sneak preview clip above shows, Cyrus, 19, can't help but overshare as soon as she meets Alan (Jon Cryer). "Hi, I'm Missi. Everyone thinks it's short for Melissa, but it's actually short for Mississippi -- the river, not the state," Cyrus chirps. "According to my parents, I was conceived on the deck of a gambling boat when my daddy won $5,000 on Caribbean poker. Have you ever been to the Caribbean?"
Acting as the love interest for Jake (Angus T. Jones), Cyrus found the filming of their kissing scenes rather awkward. "The prop guys would always [ask] 'Do you have your [engagement] ring on?' and I'd be like 'I have to take my ring off to make out with Angus? This is creepy!'" Cyrus -- engaged to Hunger Games' Liam Hemsworth -- told Leno.
Later, once Cyrus was able to channel Missi, their interactions came easy. "At first, I pictured him as that eight-year-old [from early Two and a Half Men] days, [but in this episode] his character comes back from the military with a shaved head, and it was kind of awesome."
