After roughly two months in treatment, pop star Ke$ha has come home from rehab, and the "Timber" singer is back and better than ever.

Last night, Ke$ha re-emerged on Twitter with a new, positive handle, thanks for her fans and plenty of rainbows.

Previously listed as @keshasuxxx, the pop star's new Twitter name is the simple @KeshaRose, showing that she's made positive lifestyle changes since entering rehab in January. She also updated her bio to "I'm a rainbow" and got a colorful new profile picture on the social media site (seen above).

Her first tweet since leaving her Illinois rehab center was a photo of her on a plane, with the simple caption of "meow," surrounded by emoji rainbows.

"Happy to be back! Feeling healthy & working on tons of new music. I can't thank my fans enough for all the love & support u have given me," she wrote. "Life is beautiful. I'm so blessed to have u all."

Ke$ha has successfully completed rehab for bulimia, after admitting herself into an Illinois treatment center shortly after the new year.

While in treatment, she sent several messages to her Animals on Twitter thanking them for their support, both from herself and a friend proxy.
