If you remember just a few months ago last year, Avril Lavigne filed for divorce from her husband of three years, Deryck Whibley, due to “irreconcilable differences.” Since then, Avril has been seen out in public partying hard with a group of girls, and sometimes, even, flirting with different men, as if she were celebrating her being newly single. The Sk8r Boi singer was also rumored to be flirting with The Hills star Brody Jenner and actor Wilmer Valderrama.

But then again, just last month, at the world premiere of the movie Alice in Wonderland, the former teen star arrived at the after party with an unlikely companion–her ex-husband! Both singers were looking very much like a couple at the said event. The two even left the party and headed back to Avril’s hotel together.

So, are they back together or not? Now, while waiting for an answer, why don’t you go and check out more Avril Lavigne’s scandalous pics here!
