Katy 'proud' of drug-free Brand

Katy Perry has sent ex-husband Russell Brand a congratulatory message to celebrate his 10 years off drugs.

The 'Wide Awake' hitmaker - who divorced the British comedian in December 2011 after 14 months of marriage – sent the 37-year-old actor an email detailing how "proud" she is of him for being sober for a decade and told him her heart is "finally healing" following their split.
