Paris Hilton presented her mother Kathy with a gift to soften the blow before revealing that she had been keeping a major secret. The 42-year-old heiress and her husband Carter Reum kept their son Phoenix Barron's existence hidden from almost everyone — including their families — until after he was born via surrogate in January. In a new interview with Rolling Stone, Hilton recalled inviting Kathy over "as if it was any regular day" before giving her a blue Chanel bag and introducing her to her grandson for the first time.
