"You taught me what being a mom was all about and you were there first. I love you more than I can say.

I love you more than life itself, you don't even understand how much I love and adore you and I appreciate you.

"You were the biggest blessing in my life and I thank you Kourtney. And let's all celebrate Kourtney's birthday."

The whole group had their faces turned into Piñatas and they spent the night sleeping on an airstream inflatable bed in a silver truck that had been turned into a luxury mobile home.

The party came Kourtney enjoyed an ice cream birthday celebration on her actual birthday with her three children, Mason, eight, Penelope, five, and three-year-old Reign - who she has with ex-partner Scott Disick - at Taverna Tony in Malibu, California.

The feast was documented on Instagram Story, with Penelope carrying out a huge platter of ice cream as the group sang 'Happy Birthday' to Kourtney.

Once they returned home, Kourtney was delighted by a rose gold balloon display that read "Happy Birthday, Mom".

And on Tuesday, the 'Keeping Up with the Kardashians' star marked the occasion a day before with her sisters Kim, Kendall and Khloe, while visiting the 'Revenge Body' star and her new baby daughter True in Cleveland.

She shared a photo of a pink cake decorated with roses and berries, the words 'Happy birthday Kourtney', and two gold candles on her Instagram Story and wrote: "It's my birthday tomorrow!! Thank you @khloekardashian (sic)"

And that wasn't the only sweet treat Kourtney received as she also shared a photo of some colourful mini donuts which spelled out 'Happy Birthday Kourtney'.

The excited star also posted a photo of herself and half-sister Kylie Jenner hugging and laughing at Coachella over the weekend and wrote: "It's my birthday tomorrow."
