"The rehab RUMORS are hilarious!" she tweeted on Tuesday night to her 17 million-plus followers. "The only thing I'm addicted to right now is Bing Crosby." Watch the video above for more details.
Showing her holiday spirit, she added: "MERRY CHRISTMAS EVERYONE! and to all a goodnight!"
Rumors that Lavigne was sick spread after a fan account started tweeting out hashtags "#PrayForAvril" and "#GetWellSoonAvril." The pop star may have fueled the rumors a bit by tweeting back: "Thank you."
The fan account also shared direct messages that were allegedly from Lavigne. "I feel bad because I haven't been able to say anything to the fans to let them no why I've been absent," the alleged private tweets read. "I'm torn as I'm quite private…I'm not feeling well. I'm having some health issues. So please keep me in your prayers."
Despite all the rumors, Lavigne seems to be ready for Christmas. Earlier this week she posted a "Happy Holidays" card that showcased her punk rock style and her all-boy band.
