As Katy Perry
The singer tweeted on Saturday - her first post since her estranged husband Russell Brand filed for divorce in late December - that her spirits had been lifted by kind words sent to her from across the globe.
"I am so grateful for all the love and support I've had from people around the world," she wrote. "You guys have made my heart happy again."
Brand filed for divorce from Perry on December 30, citing irreconcilable differences. Even before he filed, though, there was widespread speculation that the two were having problems.
Following the news, the rumors only increased as the media tried to pin down a reason for the couple's split after just a little more than a year of marriage.
However, Perry warns her fans to not believe what they hear unless it's coming from her. "Concerning the gossip," she said Saturday, "I want to be clear that NO ONE speaks for me. Not a blog, magazine, 'close sources' or my family."
