Avril Lavigne and Chad Kroeger have separated ... but it didn't look that way Thursday night.
The estranged couple left the Sunset Marquis together in WeHo, 3 months after announcing their separation.
There are a few scenarios ... obviously they could have had a change of heart, or they took a page out of the Gwyneth Paltrow and Chris Martin handbook.
Cool - hopefully the adversity and turmoil can go into her music, and improve the reception it's been getting this decade and perhaps lead to some critical acclaim or Grammy nominations - maybe even her first win?
