Russell Brand's tribute to Amy Winehouse
The actor has posted a blog on the singer whom he knew well
Tributes from the stars have been pouring in from all over the world to express sadness over the premature death of singer Amy Winehouse.
Actor Russell Brand has posted an entry on his website, http://www.russellbrand.tv, titled "For Amy", in which he recounts the first time they met.
Brand comes from a point of understanding, as like Winehouse, he too had to battle his addictions in the past, and the comedian speaks of his own demons in this open letter about the jazz singer.
"I was myself at that time barely out of rehab...." writes Brand "so I barely reflected on the now glaringly obvious fact that Winehouse and I shared an affliction, the disease of addiction"
The Christian Grey actor admits he's open-minded about saucy fantasies... even if a Fifty Shades Darker life isn't for him!
Heart's Emma Bunton, Katy Perry and Alexandra Burke tweet tributes after Amy is found dead at her London home.
