The US couple were pictured arriving at the glitzy event in Los Angeles and hugged and smiled as they posed for photographers.
Robin looked seriously dapper in a tux, complete with his trademark aviator sunglasses, while Paula glammed it up in a monochrome sequinned dress.
It was a massive night for Robin, as he took to the stage at the Staples Centre and performed a medley with old school band Chicago.
They first did a rendition of Chicago's song 'Does Anybody Really Know What Time It Is?' before moving on to Robin's huge hit 'Blurred Lines'.
Thankfully, Robin's performance was nothing like his controversial duet with Miley Cyrus at the MTV Music Video Awards last year. Phew!
Although he didn't walk away with a gong, Robin was nominated at the Grammys for 'Record of the Year', 'Best Pop Duo/Group Performance' and 'Best Pop Vocal Album'.
