Mommy's big day! Kate Gosselin celebrated her 40th birthday back in March, but on Tuesday, June 23, fans will get to see the reality star's sunny Mexican getaway with her eight children. 

The family stayed at the Karisma Hotels & Resorts Generations Riviera Maya where the mother of eight got to soak up some downtime while her kids stayed busy. 

Gosselin's 14-year-old twins and 11-year-old sextuplets helped out in the Little Eko Chefs Kitchen, decorating gourmet birthday cakes for their mom. 

The family then had a private birthday lunch at the Haab restaurant, but Gosselin also got some kid-free time with a close pal as they cruised into Playa Del Carmen in a stretch Navigator for a night out. 

Kate Plus 8 airs Tuesday, June 23, at 10 p.m. ET on TLC.
