“Gucci Gang” rapper Lil Pump splashed out on a $25,000 limited-edition bike by Gucci.

We hear that Pump was shopping at TheArsenale in Miami, which sells luxury goods from high-end skateboards to airplanes, when he picked out the pricey white bike with custom logo details this week.

“He was talking about coming back in to look at a $2.5 million submarine,” said the source.

“He seemed part joking, part serious. He was saying he might have to go ‘underground’ for a bit.”
