Brody Jenner received a surfboard-themed cake for his birthday.

Brody Jenner along with girlfriend Avril Lavigne celebrated Jenner’s birthday in Sin City Sunday night at The Bank Nightclub at Bellagio.

Jenner, the American television personality and son of Olympic decathlete Bruce Jenner, celebrated his 28th birthday at The Bank Nightclub at Bellagio with his rocker girlfriend Lavigne and a group of friends from Los Angeles including former “The Hills” alum Frankie Delgado.

The couple arrived in Las Vegas coming straight from Jenner’s step-sister Kim Kardashian’s highly anticipated wedding with New Jersey Nets forward Kris Humphries. After tweeting to his followers, “The ship has arrived! VEGAS TIME BABY…Gonna be a great one,” the couple joined their friends for a special group dinner at Yellowtail Japanese Restaurant & Lounge at Bellagio, where the two were spotted cuddling with each other at the table while enjoying Yellowtail’s greatest hits, the Big Eye tuna pizza, rock shrimp and lobster carpaccio by Executive Chef Akira Back.

The group ended their feast by singing “Happy Birthday” to Jenner in Yellowtail’s private dining area. The group then made their way to The Bank Nightclub where they hung out in their VIP section dancing to the sounds by DJ Karma.

While at his table, Jenner was presented with a West Coast beach-themed birthday cake decorated with surfboards, palm trees and the names of Jenner’s favorite surfing spots in California, while Lavigne and his friends toasted the birthday boy. Later in the evening, Jenner and Lavigne chatted with American rapper Gucci Mane, who stopped by their table before getting behind The Bank’s deejay booth to give an impromptu performance of his smash hit “Wasted” to the packed crowd. After enjoying the lively performance, Jenner and Lavigne finished the evening taking one last round of birthday shots with their group before leaving The Bank around 4 a.m.
