I wonder what they all talked about .

Leonardo DiCapriocelebrated his 49th birthday this past weekend!

Which, like, wow! It seems like only yesterday he was posing with Twix candy bars.

To celebrate his bday, Leo had a big ol' party in Beverly Hills, and I was surprised at who showed up…

First off, and of course,Tobey Maguirewas there.

Kim Kardashiangot an invite.

Sara Gilbert was there.

Chris Rockwas there.

Lil Waynewas there, too.

Olivia Wilde turned up.

Salma Hayek was there.

Corey Gamble left with a cigar.

That’s Emile Hirsch.

Harry Jowsey fromToo Hot to Handlewas there.

Obviously, Leo’s mom, Irmelin Indenbirken, got an invite.

Casey Affleck and Caylee Cowen wore blue.

Jennifer Meyer was there.

Scott Eastwood was there.

Snoop Dogg was there.

That’s Lady Gaga.

Kate Beckinsale showed up dressed as a big ol' jewel.

Zoe Saldaña and Marco Perego showed up together.

Beck was there.

Zack Bia was there.

That’s Rita Ora and Taika Waititi.

Soleil Moon Frye was there.

Tyga was there.

That’s Kevin Connolly.

That’s Luka Sabbat.

And lastly, Channing Tatum and Zoë Kravitz were there.

The only person who wasn’t there was Kate Winslet, and to be honest, it really disappoints me!
