It seems the cold London air -- and two stints in rehab -- have done Kelly Osbourne's body good.

The 23-year-old was spotted outside her North London home on Tuesday, looking pretty fierce -- in a "Superman II" villainess sort of way!

Now if only she could work her makeover magic on BFF Amy Winehouse.
