Singer Avril Lavigne's marriage to musician Chad Kroeger have reportedly hit a rough patch. However, the couple is still working to save their relationship.

The two have been fighting a lot and they're having a lot of trust issues, reports eonline.com.

"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. 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," said an insider.

`And now that 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," the insider added.

The duo's issues extend beyond their professions, however, and it seems as though trust and timing are two things that Lavigne and Kroeger have problems with.

"There's jealousy on both sides. She flirts, he flirts. She's very insecure to begin with. I think for now they're going to try to work it out," said the insider.
