scarf jeans sunglasses boots shopping Kourtney Kardashian

Fresh from son Mason's big 2nd birthday bash, Kourtney Kardashian is ready to catch up on her Christmas shopping, and treat herself to a little Gucci splurge!

The reality star and partner Scott Disick threw their son Mason an extravagant 75-guest birthday party at Bruce and Kris Jenner's home in Calabasas last Saturday, and they even hired Kim K's wedding planner for the occasion!

The theme was "Wild Wild West" and there were haystacks, ponies, goats and pigs in the family's front yard -- Mason's own little private petting zoo!

And what was the birthday boy's "best" gift? Uncle Rob surprised him with a miniature grand piano. What 2-year-old boy wouldn't love that?
