Mouseketeers don't stay squeaky clean forever.
Ashley Tisdale has been bombarded with thousands of tweets by an obsessed fan — who then turned up at her home, according to reports.
Cops allegedly launched a probe after the super-fan sent 18,888 tweets to the "High School Musical" star dating back to November 2012.
One tweet reads: “My body is yours & even as friends I f***** love how I make u feel like mom maybe we both got issues cuz nobody’s perfect.”
The suspected super tweeter is said to have shown up at Ashley’s pad, although it’s not clear whether he made contact.
A suspect has reportedly been identified and cops are looking to talk to him to determine whether he poses a serious risk to the star.
