This rockstar romance may be coming to an end. Avril Lavigne and Nickelback frontman Chad Kroeger are headed for a split after a year of marriage, insiders reveal exclusively in the new issue of Us Weekly.

"It's over," a source tells Us. "He has been going around L.A. telling people that they are divorcing."

Kroeger, 39, popped the question to Lavigne, 29, in August 2012 after dating for a month. They wed in an intimate ceremony in the South of France in July 2013.

Despite their troubles, the couple have yet to hint about a strain in their relationship in public. In July, the Canadian singer gushed via Twitter about the 17-carat emerald-cut ring Kroeger gifted her for their first wedding anniversary.

Lavigne was previously married to Sum 41 singer Deryck Whibley from 2006 to 2010. She dated Brody Jenner for two years until their split in January 2012 and was previously linked to Wilmer Valderrama.
