And baby makes four.
Barron Hilton, 32, and his wife, Tessa Gräfin von Walderdorff, welcomed their second child, Caspian, on Sunday.
“We are thrilled to welcome our little boy, Caspian Barron Hilton,” the couple said in a statement to People. “Milou is so excited to be a big sister!”
The couple, who waited for the baby to be born to find out the gender, say their son’s unique name signifies strength and expansion.
The son of hotel magnates Richard and Kathy Hilton and Tessa, 28, announced in February that they were expecting, saying the pregnancy was “unplanned”, but “they realized the best things in life are never.”
The couple welcomed their first child, daughter Milou Alizée, in March 2020.
“The baby is expected at the end of the summer, which will mean that Milou and baby will be exactly two and a half years apart,” they told the outlet.
Tessa announced the birth of their first child on Instagram and later revealed the special meaning of their daughter’s name.
“We found the name Milou from where we met – Pointe Milou in St Barts. We just thought it was fitting,” the couple told People at the time.
They previously revealed that they also fathered their daughter in St Barts – where they tied the knot in 2018.
“Her middle name, Alizée, means ‘trade winds’ in French. The wind of the island brought us together and a few years later it brought us Milou. She is a gift from the island.”
Hilton’s heir posed the question to von Walderdorff in 2017 while the pair were taking a stroll through Central Park in New York City.
