Benji Madden reportedly ''can't stand'' being teased about Cameron Diaz.

The 'We Are Done' hitmaker's friends can't resist poking fun at him for dating the A-list actress and joking that he has changed since they got together earlier this year.

A source told the US edition of OK! magazine: ''His friends tease him about being henpecked. They're calling him Senor Diaz and slamming him for being 'so A-list now.' He can't stand it.''

The 35-year-old rocker, who is rumoured to have secretly proposed to the 'Sex Tape' star last month, is still adjusting to Cameron's high-profile lifestyle and they have allegedly been arguing about who to invite to their wedding.

The insider said: ''Benji would love to just marry her in a drive-through chapel.

''All the friends he wants to invite have to go through a rigorous security screening, and it's embarrassing for Benji.

''Benji had no idea what dating someone so famous would be like.''

The couple got together in May after being introduced by Nicole Richie, who is married to Benji's twin brother Joel Madden.

Asked if she set them up, she previously said: ''Yes. I'm going to take responsibility for everything!''
