Taylor Swift has brought back her hip-hop alter ego T-Swizzle to accompany rapper LL Cool J at the 2012 Grammy Award nominations ceremony.

The country-pop star debuted T-Swizzle three years ago in a comedy adaption of her song Love Story with rapper T-Pain.

She was co-presenting with LL Cool J at the 2012 Grammy award nomination announcements last night when he asked her to make a hip-hop comeback.

Swift reluctantly beat-boxed while the rapper warbled a version of her hit song Mean.

"I'm like 100 per cent sure that we're not going to be nominated for that collaboration," Swift said.

The singer was nominated for a Grammy as well, with her song We Are Never Ever Getting Back Together a contender for Record of the Year.

She is up against Kiwi star Kimbra, who is nominated for her collaboration with Gotye on his hit Somebody That I Used To Know.

The Black Keys were the big winners with five nominations, including Album of the Year for El Camino and Record of the Year for Lonely Boy.
