Popstar Ke$ha -- Like You've Never Seen Her Before ... Glamourous!

Believe it or not, but "sleazy" popstar Ke$ha put away her usual ragged outfits, torn stockings, morning-after smeared makeup and ratty weave to do her best Blake Lively impersonation by bathing and glamming it up at an event in Beverly Hills last night.

The 25-year-old looks great, now if she could only do something about her music.
