Avril Lavigne and Nickelback frontman Chad Kroeger are allegedly headed for divorce after just one year of marriage, Us Weekly reports.

According to a source from E! News, Lavigne and Kroeger "have been fighting a lot" and "they're having a lot issues."

"The main issue is this: When they met, they were in work mode. They were doing a collaboration and that's where the attraction stemmed from. She was in the studio and he was producing her [album]. She was also coming off some bad relationships where she didn't really feel appreciated as an artist. She felt she and Chad connected on that level," the E! News source reveals.

The source continued to add that because "the album didn't do as well as they had hoped, they're finding that they're not seeing eye to eye on a lot of things."

In addition to not "seeing eye to eye" in work, the couple is also allegedly dealing with issues of infidelity.

"There's jealousy on both sides. She flirts, he flirts. She's very insecure to begin with," the E! News source revealed.

An Us Weekly source also dished on the couple's tumultuous relationship, adding "It's over. [Chad] has been going around L.A. telling people that they are divorcing. Chad is just a complete jerk in the way he talks to her, and the way he talks to people in general. A lot of her friends don't like him."

Kroeger and Lavinge announced their engagement back in August 2012 and later married in the South of France in July 2013, Us Weekly reports. Since then, the couple has shown no sign of strain in their relationship.

In fact, according to Us Weekly, Lavigne even tweeted a post back in July regarding her excitement over the 17-carat emerald-cut ring that Kroeger gave her as a 1-year anniversary present.

The couple has yet to announce their divorce.
