Kourtney Kardashian got really spoiled on her birthday this year. The reality starlet had two parties this week to celebrate turning 34 on Thursday, Apr. 18.

After kicking off her birthday by going bowling with her family on Wednesday, the whole Kardasahian clan treated Kourtney to a second party on Thursday. "The Fam getting ready to surprise Kourtney for her birthday! Shhhh," sister Kim teased on Twitter. She included a photo on Instagram of herself posing with Khloe, Lamar Odom, Kris Jenner, Bruce Jenner, Kendall Jenner, Kylie Jenner, Brody Jenner, Brandon Jenner and his wife Leah Felder while waiting for the birthday girl.

After the surprise, Kourtney also shared several pictures from her party on Instagram. Though he didn't make it into the group photo, Kourtney posted a cute snapshot of herself posing with longtime boyfriend Scott Disick. The couple's two children, Mason, 3, and Penelope, 8 months, didn't appear to be in attendance.

Kourtney's family also surprised her with a giant birthday cake that looked like stacked Hermes gift boxes. "And that's a wrap," Khloe joked on Instagram with a shot of the cake.

Sister Kim has even more reasons to be celebrating this week. On Friday, the 32-year-old star, who is pregnant with her first child with Kanye West, finalized her divorce from Kris Humphries after 536 days.
