Miley Cyrus has an upcoming cameo on Two and a Half Men which will find her locking lips with 19-year-old Angus T. Jones. Which wouldn't ordinarily be a big deal except, well, she's engaged to Liam Hemsworth and all.

During an appearance on The Tonight Show with Jay Leno she told the iconic late night TV host that shooting the kissing scenes with Jones were definitely weird. Only because the production crew kept joking with her about her engagement ring.

Check out what she had to say.
