Tessa shared the first photos of baby Caspian on Instagram just days after his birth last September, writing, "Welcome to the world our little boy 💙 Caspian Barron Hilton 💙 Born 09/04/2022."
She also included an adorable picture of their daughter giving her baby brother a kiss on the head.
Earlier this month, she shared a sweet tribute to her son on Instagram in celebration of his first birthday.
"Happy 1st Birthday to our darling, smiley, sweetest, most loving and enchanting little prince, Caspian. I am so lucky you chose me to be your mother 💙."
Tessa and Barron met in St. Bart's in 2016 and tied the knot there two years later. Their latest addition comes amid a baby boom in the Hilton family.
