you are an alien on the run from the galactic space police
they know your name
you escape to earth to hide while working towards some crazy plan to destroy the galaxy
...by taking on the identity of a fairly high profile individual in the entertainment industry AND USING YOUR REAL NAME AS PART OF YOUR ALIAS
and then it takes the space police chick 6 months to even locate the guy while living on earth herself
