Lisa wrote a letter of love for her daughter, who turns 30 on Saturday, and her 24-year-old son for TIME in honor of Mother's Day. In it, Lisa opens up like never before about what motherhood means to her. "The bond I have with you both, it is something totally different to any other relationship I have ever had," Lisa wrote. "The freedom as a mother to nurture, to climb into your bed and whisper deep into your ear, 'Mummy loves you,' to love unabatedly, unapologetically, and to feel a sense of pride as you passed milestones in your life, as if it were my own achievement."
She also had an important message for her son Max, who she and husband Ken Todd adopted. "Max has shown us that biology has little to do with a mother’s bond," Lisa wrote.
The Vanderpump Rules boss went on to explain the bittersweet process of getting her children ready to leave the nest. "I felt exasperation as I repeated the same thing every day, 'Please pick up your backpack! Don’t leave it in the hall,'" she continued. "And then one day that backpack is gone and I would do anything to see it strewn across the floor."
And yes, growing up a Vanderpump-Todd meant there were always a lot of animals around. "I made the rules at home and we loved breaking them—ponies in the kitchen, ducks in the bed, midnight feasts, riding bareback in pajamas through the village, a journey that was filled with ridiculous scenarios that only we could enjoy, because you were mine and you were the best playmates a mother could have," Lisa wrote. "So I thank you for that."
It sounds like Lisa couldn't be more grateful to be Pandora and Max's "mummy." "You have enriched the fabric of my life, you have colored it, you have given me so many memories that I have harvested for a day when my life might not be so vibrant," she wrote. "And so on this Mother’s Day I want you to know, it is an honor to be your mother, a job I will always cherish. I thank you both."
