Avril Lavigne's scared admirer

Avril Lavigne's husband has warned Paris Hilton's ex-boyfriend to stay away from her.

Rocker Deryck Whibley was reportedly furious after he discovered Avril had been out for dinner with oil heir Brandon Davis - who has also dated Lindsay Lohan - and texted his love rival saying: "Stay away from my wife."

However, a source is quoted by gossip blogger Perez Hilton as saying: "Avril assured Deryck that it was a business dinner about art, since Brandon also makes a living as an art broker. Deryck trusts his wife, it's just Brandon he doesn't trust."

Avril and Deryck have recently been dogged by rumours their two-year marriage is in trouble.

The 'Girlfriend' hitmaker was spotted at actor Jamie Foxx's birthday party alone, further fuelling break-up speculation.

Despite their apparent troubles, Avril has also prompted reports she is expecting her first child with her musician spouse after she refused alcohol during a recent night out.

Avril - who has also been photographed with what appeared to be a baby bump - only guzzled soft drinks while at exclusive Hollywood nightspot Coco De Ville.
