Avril Lavigne Slams Rehab Rumors

The singer calls the rumor "hilarious," but reveals one addiction.

Lavigne, 30, took to Twitter two weeks ago to tell fans she was "not feeling well. I'm having some health issues. So please keep me in your prayers."

The "Complicated" singer now wants people to know one rumor in particular is bogus.

She still did not specify what has been ailing her. Fans have reacted in support of Lavigne with the hashtags #PrayforAvril and #GetWellSoonAvril.

A rep for Lavigne had no comment about the illness.
