Taylor Swift may be Down Under, on tour in Australia, but the singer beamed in and performed her smash hit 'I Knew You Were Trouble' at 'The Grammy Nominations Concert - Live!!' which aired tonight (Dec. 6) and took place in Los Angeles.

Swift co-hosted last year's event, held in Nashville. Since the singer's touring commitments kept her out of the country, she still took care to include the Grammys in her evening with her sassy performance, which featured her changing costumes mid-song!

We may not have been able to see Swift in person in Australia, so she brought Oz to us.

Swift has already been nominated for a 2014 Grammy -- 'Red' was recognized in the Album of the Year category. Congrats!
