The Happy star is a big fan of the Royals hitmaker, and is desperate to land a collaboration with her.
Speaking during an appearance on Australia's Sunrise Tv show, he says, "When you hear Lorde's music you hear her lyrics, you hear her melody and you hear her music but you also feel what she's saying... Oh man! I would love to work with her. She doesn't need me but I would love to work with her..."
Williams has previously collaborated with some of the world's most famous music stars including Madonna, Beyonce, Justin Timberlake, Miley Cyrus and Britney Spears, as well as his most recent hits with Daft Punk and Robin Thicke, and the former N.E.R.D member has two more big names on his most wanted list.
He adds, "Prince has always been a dream to try and collaborate with... my son loves Katy Perry so I suppose that makes all the sense in the world."
