Paris Hilton, Lil Wayne duet in 'I Wanna Bang You' - listen
The leaked track is reportedly named 'I Wanna Bang You', and is intended for Hilton's long-awaited second studio album, reports TMZ.
The pair make reference to Hilton's infamous sex tape in the track, which includes the lyrics: "Last night was awesome / Super f**king awesome / It was me, myself, and I, and her / We had ourselves a foursome."
Lil Wayne adds: "Excuse my french, but f**k the cameras / I wanna spend a night in Paris."
Paris Hilton's follow-up to 2006's Paris was expected to be released in summer 2011, but it has yet to materialise.
She named Lil Wayne as a potential duet partner back in March 2011, while also confirming a collaboration with Snoop Dogg.
