Avril Lavigne and Chad Kroeger set to divorce less than a year after marriage

Less than a year after marrying, Canadian rockstars Avril Lavigne and Chad Kroeger are reportedly set to divorce.

Speaking to Us Weekly, a source said: "It's over.

"He has been going around L.A. telling people that they are divorcing."

Time apart has been a regular occurrence for the couple because of their respective music careers, but this had previously thought to have proved no obstacle to maintaining a happy marriage.

At the beginning of August, 29-year-old singer Avril flashed a huge diamond ring, a one-year anniversary gift Chad gave her, to her 16.3 million followers on Twitter, one month after she celebrated a year of married bliss.

However on Wednesday the picture had been deleted.

The Canadian couple, whose wedding was covered exclusively by HELLO!, described their big day at the time as "unforgettable".

For Chad, who proposed to Avril just one month into the relationship, marriage was always on the cards. "It felt like the stars had aligned. It felt like fate was intervening and I was being given this wake-up call: don't let this one get away. And I think she felt the same way and that's why I proposed in such a short time span – because we wanted to start our lives together."

The pair also had rules they both abide by to keep their romance on track.

"We don't go more than two weeks without seeing each other," Avril told People magazine.

Her 39-year-old partner added: "And we don't drink when we're apart." The couple said that putting themselves in a position of temptation was something they were not willing to do as they value their union too much.

"We don't want to go anywhere that you're asking for trouble," Chad added. "This is something that we want to cherish and protect."
