Miley Cyrus' Eventful "Favorite Day" - Friday the 13th

Bringing an end to the work week, Miley Cyrus certainly had her pleasant and not-so-pleasant moments throughout the day today (July 13).

The former "Hannah Montana" star woke up in a chipper mood, as she posted an adorable photo of herself alongside her bulldog pup Ziggy with a message reading, "Good morning twitter xo Zigz ".

Shortly thereafter, Miss Cyrus ran into a frustrating situation as she found herself as having lost all of the digits to her friends and loved ones. Of the situation, the 19-year-old tweeted, "Ugh! So irritated I lost ALL my contacts! Text me if ya wanna stay friends! ;) thankkkks!"

Not letting the phone snafu get in the way of her workout regimen, Miley tossed on her trusty black leggings and a loose grey shirt while hitting up a local fitness center for her regular Pilates class.

Leaving the sweat session de-stressed and rejuvenated, Cyrus was back in fine spirits as she headed into the evening hours with a happy-go-lucky tweet reading, "Ahhh. My favorite day. Friday 13th :)"
