It was a Kardashian bash last night as the family celebrated Mason Disick's third birthday.
Even 5-month-old Penelope Scotland stepped out to ring in her big brother's special day as her mom Kourtney carried her into Serendipity's in Miami on Dec. 14.
Aunts Kim and Khloe were on hand for the celebratory dinner, as well as Mason's dad Scott Disick and pal Jonathan Cheban.
"Happy Birthday to my most precious angel who has forever changed my heart," Kourtney wrote on her website yesterday. "I will never forget the day you entered my life, three years ago. It is an honor and a joy to watch you grow every day."
Kourtney told Us Weekly that she's planning on throwing Mason another bash with all his friends when they return to Los Angeles once filming has wrapped on "Kourtney & Kim Take Miami."
"I got a cute cake and everyone got him little presents, so we'll just do something fun like that," Kourtney said.
"I can't believe Mason is turning three today!" Kim wrote on her website. "He has changed my world in so many ways and I am amazed every day by him."
"He is the world's greatest big brother to Penelope and the most loving nephew any aunt could ask for," she added. "Happy birthday Mase, love Aunt KiKi."
