These things happen … when you’re a famous rapper.

G-Eazy, 30, got a special surprise from a fan as the rapper celebrated New Year’s Eve at Miami nightclub Rockwell early Wednesday morning.

Shortly after the “No Limit” singer’s 2 a.m. arrival, an anonymous partygoer sent over a $5,000 Armand de Brignac “Ace of Spades” bottle parade, an insider exclusively told Page Six.

“He seemed surprised and excited when it arrived,” said the source.

We’re told G-Eazy was seen dancing with his big entourage before taking to the stage at around 2:30 a.m. to perform some of his hit songs, including “1942” and “I Wanna Rock.”

We hear he told clubbers, “It’s the start of a new decade. What level do you want to start this new decade on? Let me know …”

G-Eazy partied the night away until around 5 a.m.
