Baby Barker's name has been officially confirmed.

Kourtney Kardashian and Travis Barker named their son Rocky Thirteen Barker, according to the birth certificate obtained by People.

Rocky was born on November 1 in Los Angeles. Although they have not confirmed the arrival of the baby, inside sources say that they are more than happy for their family.

"She's happy to be able to hug her son now," a source said earlier this month.

Travis and Kourtney met in 2006 and became friends. In February 2021, they began a romantic relationship and got engaged months later. Last spring, they celebrated several wedding ceremonies, from a court ceremony to a luxurious weekend in Italy.

Kourtney has three children from her marriage to Scott Disick: Reign, 8, Mason, 13, and daughter Penelope, 11. Barker is father to London, 20, and daughter Alabama, 17, from his relationship with ex-partner Shanna Moakler.
