Is Avril Lavigne back with her husband? Deryck Whibley joins her at Alice In Wonderland party

After splitting from her husband last year Avril Lavigne has been linked to everyone from actor Wilmer Valderrama to oil heir Brandon Davis.

Just last week rumours spread that she was dating U.S. reality TV star Brody Jenne.

But perhaps the gossips have got it wrong. Behind closed doors it appears the Sk8er Boi singer may have rekindled her relationship with her husband of three years, Deryck Whibley.

The pair were spotted sharing a car as they left the after party following the premiere of Alice In Wonderland in London last night.

And while they weren’t caught in a steamy embrace, it certainly looked as if relations between the two were on good terms.

Avril was at the party as she sings the title song Alice (underground) for the Tim Burton film.

The track was produced and mixed by Whibley, from whom Avril filed for divorce last October, a month after their split.

The 25-year-old insisted at the time that they would stay friends.’

Deryck and I have been together for six-and-a-half years,’ she said of the Canadian music producer.

‘We have been friends since I was 17, started dating when I was 19, and married when I was 21. I am grateful for our time together, and I am grateful and blessed for our remaining friendship.

‘I admire Deryck and have a great amount of respect for him. He is the most amazing person I know, and I love him with all my heart.’

Deryck and I are separating and moving forward on a positive note.’
