Disney star Tiffany Thornton is pregnant with her second child.

The actress announced the happy news with a cryptic note on her WhoSay account, accompanying a photo of herself and a group of pals.

She wrote, "Guess what?! Hint: why am I holding my stomach?"

The 27-year-old Sonny with a Chance star and her husband of two years, Christopher Carney, welcomed son Kenneth James last year (12).
