Megan Park and her bestie, Miley Cyrus, are busy promoting their new flick So Undercover (set for an October release), but we only have one thing on our minds: Secret Life of the American Teenager!

Now that the first half of Season 4 is officially dunzo, we’re dying to know what’s in store when Secret Life comes back in 2012.

"There's a bunch of new characters coming in that throw things around,” Megan reveals. “And then there's some characters leaving, so there's a lot of new stuff happening.”

We can’t wait to meet Grant High’s new blood, but what’s with these mystery characters who are leaving the show? Ricky, Jack, and Adrian are all going off to college, but there’s no way the Secret Life writers would write them off, right?
