So when her son, Phoenix, marked a very special milestone, there was no stopping her.

“Sliving under the sea with Baby P for his first birthday!” Paris posted alongside photos of his party, held at the Beverly Park, Calif., mansion she shares with her husband of two years, Carter Reum.

“A magical day for the most magical smiley boy,” she wrote. “My life is forever changed thanks to you, Phoenix! Thank you for making me the luckiest #SlivingMom.”
