Rapper Lil Wayne has sparked rumours of a feud with 50 Cent after making disparaging comments apparently aimed at the In Da Club star on a new mixtape.

The Lollipop hitmaker appears to take lyrical jabs at his rap rival on a freestyle titled Louisianimal from his The Drought Is Over mixtape.

On the track, he raps, "All about a dollar, f**k two quarters" - lyrics understood by fans to be a swipe at 50 Cent's stage name.

Lil Wayne continues to take aim at the superstar's endorsement of Vitamin Water, saying: "B**ch, I'll pour syrup in that Vitamin Water."

He goes on to add, "I hope you die ugly, and tonight will be gorgeous."
