London: Pop star Avril Lavigne has been diagnosed with a throat infection, but the singer is not letting it come in the way of her upcoming album.

The `Girlfriend` hitmaker is currently recording for a follow-up to 2007`s `The Best Damn Thing` and was dealt a setback last week when doctors confirmed she has been struck down with the streptococcus virus, reported Contactmusic.

But the 25-year-old singer is determined to battle through the illness and has posted a photo of herself wearing a medical face mask on her Twitter page.

"In the studio with (music producer) AlexDaKid, I`ve got strep throat, but I ain`t stopping my thing!" wrote Lavigne.
