It's America vs Australia as these two singers go head to head!

It's a battle of the blonde singers as the gorgeous Delta Goodrem and beautiful Taylor Swift battle it out in who wore it best!

So it's up to you to decide, will it be the Australian singer who is married to Westlife hottie Bryan or American country singer and friend of the Jonas Brothers?

Here they are...

Delta Goodrem wore the Collette Dinnagan dress to the Madison Sex, Frocks & Rock’ N ‘Roll dinner in Sydney. She wore it with leggings, YSL boots and a black shiny clutch.

Taylor wore her Collette Dinnagan dress to the 2009 Grammy Salute earlier this year. She opted for bare legs in her dress and teamed it with Louboutin peep toe shoes and a Jimmy Choo clutch.

This is a tough one! They are both soooo gorgeous, but the decision is yours?
