A series of tweets from singer Avril Lavigne has sent her fans into a frenzy speculating about her health.

It began when a tweeter sent a message to Lavigne which read, "#GetWellSoonAvril #PrayFor Avril". That same tweeter later revealed Lavigne's response: "I feel bad because I haven't been able to say anything to the fans to let them no 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."

A rep for the singer confirmed to Billboard magazine that the exchange was legit, but was quick to state that Lavigne, despite rampant rumors, is not pregnant.

Lavigne recently celebrated her 30th birthday in Las Vegas without her husband, Nickelback lead singer Chad Kroeger, leading to even more speculation that her marriage is on the rocks.

A source told E! News that there might be some credence to the rumors, telling E!, "Things still aren't good. But Avril's friends are encouraging her to try and work it out. They don't like Chad, but she's already been through one painful divorce and they don't want to see her going through another unless there's no other option. Also, she and Chad haven't been married that long so her friends want her to make sure she's given it every chance before pulling the plug."

Lavigne and Kroeger have been married since July 2013 and have no children together.

She wound up her Twitter exchange by telling her fans, "I miss you guys too!" Well, whatever it is she's going through, we wish her all the best.
