Punk-pop pair are reportedly on the verge of splitting up

Avril Lavigne and Sum 41 man Derek Whibley are on the verge of ending their two-year marriage, according to The Sun.

The newspaper claims a rift has grown between the Canadian couple since the ‘Sk8r Boi’ singer’s world tour earlier this year.

A source said: “They have been growing apart for months. Deryck isn’t motivated in his own career, so he’s been drinking and partying.”
