What is the name of Beyoncé’s son with Jay-Z?

Beyoncé’s son with Jay-Z is named Sir Carter.

Sir Carter was born in June 2017, together with his twin sister Rumi Carter. Beyoncé and Jay-Z also have an older daughter, Blue Ivy Carter, who was born in January 2012. The family’s children have occasionally appeared in their parents’ music, videos, performances, and public projects.

The names of the twins are often confused because they were announced together and both became widely reported. Rumi is the daughter, while Sir is the son. Beyoncé revealed the twins publicly in a July 2017 Instagram post that identified them by name and marked their first month. Jay-Z and Beyoncé married in 2008 and have collaborated musically many times.
