Miley's alter ego as "Hannah Montana" is on the verge of being revealed after Jackson's girlfriend spotted the pop star peeping through his window. In "De-Do-Do-Do, Da-Don't-Don't, Don't, Tell My Secret", Miley almost blows her cover when she returns from a Hannah Montana function and Siena spots her.
Siena becomes suspicious that Jackson is seeing another girl so Jackson begs Miley to tell her the truth. However, Miley says in the promo that she can't trust Siena. Meanwhile, Robby goes fishing with Rico to teach him how to relax.
This episode airs August 1 and sees Tammin Sursok from "The Young and the Restless" reprising her role as Siena. In the following week, there will be an appearance of Cody Linley who has been recurring as fellow pop star Jake Ryan. The episode is called "It's the End of the Jake as We Know It" and bears the question "Does he have a secret?"
