Kim Kardashian's baby shower is underway in Beverly Hills. We snapped the reality show star posing for pix on the back terrace at the private home where the event is being held. Earlier, we caught sis Khloe padding up to Kim's house in bare feet, and after a few last minute preparations, she hopped in her Range Rover and headed to the shower.

The bash is being held at uber-wealthy music agent Irving Azoff's Beverly Hills mansion, which is where Khloe got married (and right by the Beckham's pad). An X17 photographer on the scene tells X17online, "It's a huge production — it's like a wedding. Kim and her mom went all out on this one," adding that all the gifts guests brought in were PINK! Looks like baby Kimye is a girl after all...

The bash started around noon, an there's a huge E! production crew, three helicopters circling, lots of security and tons of photographers. Nicole Richie, Kelly Osbourne, Kimberly Stewart, Tracy Anderson and Nene Leakes are among the famous faces in attendance, and a source tells E! News that baby daddy Kanye West invited both sides of his family as well.

As of 1:45pm we still didn't spot Kanye, but Khloe told Ryan Seacrest that Yeezy is expected to show up towards the end of the shower, since it will mostly be an all-girls affair. Better late than never!

UPDATE - Kim's having a girl! The reality star revealed the baby's gender on Sunday night's Keeping Up With the Kardashians. Kim says of the news, "Kanye always wanted a little girl." Congrats!
