According to People magazine, Klum said that her most recent delivery was "easy". The star is enjoying the best time of her life, which includes her hit television show Project Runway.
On November 22, the 33 year-old beauty felt her first contraction in the morning. Klum and her husband, Seal, 43, headed for a Los Angeles hospital, and their newest baby was born by the afternoon.
Little Johan Riley Fyodor Samuel weighed 8 pounds at birth. Klum is also the mother of Henry, 1, and Leni, 2.
Having three children keeps the two stars on their toes. Klum and Seal were married in Mexico in 2005.
Heidi Klum explained, "We love that they will grow up close in age. This is what Seal and I have always wanted: a home filled with children’s laughter."
