Says she has a 'happy heart'
"I am so grateful for all the love and support I've had from people around the world," she tweeted on Saturday.
"You guys have made my heart happy again."
She also addressed all the rumours doing the rounds about how she's feeling / what she's been up to since the divorce was made public.
"Concerning the gossip, I want to be clear that NO ONE speaks for me.
"Not a blog, magazine, 'close sources' or my family (sic)."
Katy's set to appear at the People's Choice awards this week on January 11th, her first public appearance since the sad news.
