The Grammy Awards are known for their mash-up performances and to keep with the theme, Robin Thicke teamed up with the legendary rock band Chicago for a resulting standing ovation.

The band and Thicke joined forces for a dazzling performance taking the singer from the mic stand to the piano as he helped Chicago perform some classic hits and closing out with his hit, 'Blurred Lines.'

Having already performed the song at the BET Awards and the MTV Video Music Awars last year, the band breathed a breath of fresh air to the hit.

The sharp-dressed Thicke sported a dark blue suede suit and bowtie onstage. During the set, he was later joined by back-up dancers donning red skinny pants and black crop tops. The crowd inside the Staples Center was booming with applause for what can only be called as stellar.
