Avril Lavigne and Chad Kroeger might have been the picture of a happy couple since their marriage in July of 2013. Yet, the latest reports claim that the couple had split since Aug. of this year. Lavigne's alleged substance abuse problems and rehabilitation led to the marriage falling apart. How true are the reports?

Since tying the knot in July 2013, Avril Lavigne and Chad Kroeger had rarely made appearances together during red carpet events. A lot had questioned if they were still together with both singers failing to make an appearance for music awards.

Thus, a lot of tabloid reports immediately emerged claiming Avril Lavigne and Chad Kroeger are headed for divorce after only 14 months of wedded bliss. The reasons for the divorce is reportedly Lavigne's substance abuse and depression, which have led her to go into rehab.

"The buzz in her inner circle is that she's been in rehab for depression and substance abuse issues," says a source in a report by Star Magazine. "Avril was an emotional wreck over her marital problems, and she turned to partying to deal with the pain."

While Kroeger has had no trouble moving on past the decision of divorce, Lavigne has barely been able to keep herself together. Sources close to the "Skater Boy" singer claim her "world seems to be falling apart." Avril Lavigne and Chad Kroeger's alleged divorce is not the former's first as Lavigne had first divorced Deryck Whibley.

While Avril Lavigne and Chad Kroeger have been married for only a year, Lavigne had been married to Whibley of Sum41 for four years. As for the hilarious claims that she's gone to rehab that has caused her marriage to fall apart, Lavigne laughed all about it in her recent Twitter post.

"The rehab RUMORS are hilarious! The only thing I'm addicted to right now is Bing Crosby. MERRY CHRISTMAS EVERYONE! and to all a goodnight!" shared Lavigne in her tweet with regards to the Avril Lavigne and Chad Kroeger divorce and rehab reports.
