Leonardo DiCaprio was the life and soul of the party at his 49th birthday celebrations in Beverly Hills, California on Saturday.

The A-lister, 49, performed a rap and danced in front of a star-studded crowd, who gathered at a private residence in the exclusive neighbourhood.

Leo was seen being hoisted on a chair at the gathering, and later rapping into a microphone to the 1994 song DWYCK from Gang Starr and Nice & Smooth.

The Titanic leading man, who proved he is still king of the world with the iconic show, donned a black T-shirt, jeans and a baseball cap at the party in his honour.

The performance took place in a heavily decorated room full of balloons, as the cohort of celebs partied until the early hours.

The Killers of the Flower Moon star was joined by new girlfriend Vittoria Ceretti, 25, as well as Beyonce and husband Jay-Z, Lady Gaga and Kim Kardashian.

Also at the birthday bash were Salma Hayek, Chris Rock, Kate Beckinsale, Zoe Kravitz and Channing Tatum, Rita Ora, Zoe Saldana and Snoop Dogg.

The soiree drew an A-list crowd from all corners of Hollywood, from movies, music and even reality television, with a strict guest list organizers adhered to.

On a Reddit thread in which fans commented on Leo’s performance, many likened it to Succession’s Kendall Roy (played by Jeremy Strong) rapping on the 2019 episode Dundee.

‘How Kendall Roy of him,’ one user wrote, while another said, ‘First thing I thought when I saw this.’

One fan said, ‘I opened this thread literally praying this would be the top comment.’

In the storyline of the HBO show, Kendall performed in a surprise rap at an event in Scotland honouring his father Logan Roy (Brian Cox). The unexpected outing has spawned multiple memes.

One fan made another pop reference in regards to claims Britney Spears made in her book that Justin Timberlake used an inauthentic ‘blaccent’ to impress Black musicians, citing a meeting with rapper R&B singer Ginuwine.

Britney claimed that Justin said, ‘Oh yeah, fo’ shiz, fo’ shiz. Ginuwine! What’s up, homie?’ – a line quoted on Reddit in regards to Leo’s rap performance.

Actress Michelle Williams subsequently recorded passages from the Britney book with impersonations, which were popular with fans.

‘Reading that in Michelle Williams voice will never get old. That clip is so good,’ a fan said on Reddit.

The 43-year-old business mogul was spotted departing the bash wearing a sleeveless black outfit and with her face flawlessly done-up.

During the party, Leo and his girlfriend apparently packed on the PDA and were ‘affectionate and kissing throughout the night,’ according to an insider.

Zoe Saldana was joined by her husband Marco Perego as they headed to the gathering following their appearance at the Baby2Baby gala.

At one point the actor was ‘raised and carried around the room’ in celebration, as per People.

The Revenant star, his model girlfriend, and their celebrity friends kept the party going past 4am, according to the publication.

Earlier this month it was reported that Leo is ‘crazy’ about the supermodel, who turns 26 in June, with insiders claiming he is now dating her exclusively as she has ‘all of the qualities he looks for in a partner’.

Leo – who has a reputation for only dating women age 25 or under – and the Italian beauty were first linked in August, when they were seen together in Santa Barbara, California.

The pair were then spotted together again in early September, dancing and kissing in Ibiza.

Meanwhile Olivia Wilde and fellow singleton Chris Rock were seen laughing it up in the car as they left the party together.

Olivia sported a crew neck white T-shirt and rocked thin, winged black liquid eyeliner. And Chris, 58, was casually dressed in black pants, a grey crew neck shirt and a black jacket.

He flashed his megawatt grin as the unlikely pair seemed to be enjoying each other’s company.

It comes nearly one year after Olivia’s almost two-year relationship with British singer Harry Styles came to an end.

The former One Direction star is now romancing actress Taylor Russell, with whom he recently attended a U2 concert. Prior to her coupling with Styles, she was in a long-term relationship with actor Jason Sudeikis.

The two are co-parents to son Otis, nine, and daughter Daisy, seven. Their pairing came to an abrupt end when she sparked a flame with Harry while shooting her film Don’t Worry Darling.

As for Rock, he was linked to fellow comic Lake Bell throughout 2022 — and she ironically hung out with Sudeikis at a Guns ‘N’ Roses concert earlier this month.

A source also confirmed to DailyMail.com that Jason and Lake are not a romantic couple, but ‘just friends.’

Snoop Dogg, 52, was seen arriving to the bash in a black SUV as he stuck his head out of the backseat window.

Zoe and her husband coordinated in a black and white color palette. The Colombiana actress flashed her cleavage in a low-cut white dress with a black rose print throughout. The thigh-grazing frock featured an attached sarong-like wrap with a side tie.
