Leonardo DiCaprio threw a huge party for his 40th birthday in Los Angeles last night (11.11.14).

The 'Wolf of Wall Street' star celebrated the milestone with some of his closest friends, including Maroon 5 frontman Adam Levine and 'Blurred Lines' hitmaker Robin Thicke, at the SoHo House in West Hollywood.

A source said the heartthrob, who is rumoured to have split from German model Toni Garn, 22, in September after almost 18-months of dating, was also joined by Def Jam co-founder Russell Simmons and actor Tyrese at the bash.

But the insider told gossip website TMZ.com the guest list consisted of "80 percent models."

Tyrese posted a photo on Instagram of himself with Russell and the birthday boy, with the caption: "Cool as selfie - happy 40th #MyBroLeo (sic)."

Leonardo previously insisted he wasn't upset about being considered middle-aged because he still feels "youthful."

He recently: "I suppose 40 represents something different, but I've been thinking about 40 for so long that I'm prepared for it.

"It seems like the age barometer where you're still considered youthful is getting higher and higher. I'm going to hold on to that ideal as long as I can."
