G-Eazy is living the good life amid ex-girlfriend Ashley Benson’s recent engagement news.

An eyewitness exclusively tells Page Six that the rapper partied until predawn in Miami just days after the actress announced she said “yes” to oil heir Brandon Davis’ proposal.

We’re told the “No Limit” hitmaker, 34, began his Saturday night with a boujee dinner at Giselle — a new restaurant on the rooftop of nightclub E11even — alongside a large group of friends.

Our source says G-Eazy was all smiles and in good spirits as he and his pals celebrated his newly released single with Dave East, “WDGAF,” though the fellow rapper was not present.

We’re told the spicy margaritas were flowing as the group indulged on dishes like the Flaming Australian Wagyu Tomahawk, Maine Lobster Fra Diavolo, Wagyu Dumplings and Ceviche Mi Cuit — none of which are even priced on the establishment’s online menu.

After the leisurely late-night meal, our insider says the musician and his posse went downstairs to keep the festivities going at the multi-story club.

We’re told they sipped on E11even Vodka until about 3:30 a.m., at which point G-Eazy took the stage.

Our spy says the California native’s set included six or seven of his biggest tracks, including “No Limit,” and that he also delivered the first live performance of “WDGAF.”

We’re told he and his group did not leave the club until 4:30 a.m.
