Which singer had been diagnosed with Lyme disease?

Avril Lavigne (September 27, 1984) is a Canadian singer, songwriter, and actress. By the age of 15, she had appeared on stage with Shania Twain and by 16, she had signed a two-album recording contract with Arista Records worth more than $2 million. Her debut studio album, "Let Go" (2002), emphasized a skate punk persona that has earned her the title "Pop Punk Queen", from critics and music publications, due to her achievement and impact in the industry. Lavigne is considered a key musician in the development of pop punk music, since she paved the way for female-driven, punk-influenced pop music.

In April 2015, Lavigne revealed to People magazine that she had been diagnosed with Lyme disease after her 30th birthday in 2014. In an interview with Billboard that same month, Lavigne said that she was in the recovery process and that she wanted to increase awareness of the disease.
