Fans reacted in support tweeting the hashtags #PrayforAvril and #GetWellSoonAvril.
A rep for Lavigne had no comment about the illness.
Lavigne married fellow rocker and Nickelback's lead singer Chad Kroeger last summer and when she wasn't seen out with her husband in weeks, rumors of relationship woes started to circulate.
Over the weekend Lavigne thanked her fans for the support.
