Avril Lavigne may have just revealed that the reason why she hasn't released any new music in over a year, nor been seen in public for quite some time, is because she is suffering with an undisclosed illness.

The Canadian singer first hinted that she was having issues with her health during a Twitter exchange with a concerned fan over the weekend, as she asked the user to "keep me in your prayers." But Lavigne did not identify the illness nor release a statement on the matter.

Twitter fan account @AvrilMusicChart shared a screenshot of a DM exchange that occurred on Saturday (Dec 6th), in which the fan asked if Lavigne has been quiet as of late because she is working on new music in the studio.

Lavigne responded, "I feel bad because I haven't been able to say anything to the fans to let them no [sic] why I've been absent. 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."

On Sunday (Dec 7th), the fan posted a tweet that read, "#GetWellSoonAvril #PrayForAvril," and Lavigne replied once again with a simple "thank you." Since then the many fans have also posted the hashtag, along with well wishes to the 'Hello Kitty' singer.

A rep for Lavigne confirmed to Billboard that the DM exchange was authentic, but the 30-year-old's health issues were not revealed, apart from confirmation that she isn't pregnant.

The female rocker last released her self-titled fifth studio album, featuring the singles 'Here's To Never Growing Up' and 'Rock N Roll,' in November 2013.
