Singer Katy Perry and Russell Brand
“Although they’ve broken up, Katy knows how important this milestone is for Russell,” the Daily Mail quoted a source as telling the Sun.
“She wanted to let him know that she was thinking of him and that she was still proud of what he has achieved,” the source said.
Brand, 37, wrote on his Twitter account last week, “10 years clean today. Thanks for all your messages of love. Thanks @schullerinc for the film. Anyone can get clean, one day at a time.”
