Tragic Details About Avril Lavigne

As if being bedridden with Lyme disease wasn't bad enough, Avril Lavigne went through another divorce during this time. When she spoke to People in 2015, Lavigne said that both her mom and her then-husband, Nickelback frontman Chad Kroeger, were helping to care for her. However, Kroeger apparently found it hard to be there for her all the time since he was touring. It's not clear whether Lavigne's Lyme disease was the cause of their split, but, in September 2015, Lavigne took to Instagram to break the news that she and Kroeger were divorcing. "It is with [a] heavy heart that Chad and I announce our separation today. Through not only the marriage, but the music as well, we've created many unforgettable moments. We are still, and forever will be, the best of friends, and will always care deeply for each other," the now-deleted post read.

Despite the terrible timing of the divorce, it appears that Lavigne and Kroeger remained friends, with Lavigne even defending him when Facebook CEO Mark Zuckerberg took a very public jab at Nickelback. Kroeger also worked on Lavigne's comeback album, "Head Above Water," so, clearly, there isn't bad blood between the two.
