Transaction details to multiple email adresses

When someone makes a transaction on my site I need the details to be emaild to 3 adresses.

1 - My adress,
2 - A friends adress
3 - the person who is making the transaction.

it appears as tho by default opencart informs the person who is making the transaction and myself. Is there an automated way to send the same details to a friend as he will also need the order details to process the transaction.

Cheers,
Sam

I really need help with this, if anyone can help i would be forever greatful
