Paris Hilton and her husband, Carter Reum, have become parents again, this time with a daughter. Paris published a photo on Instagram, where she wrote: "Thankful for my baby" and revealed that the girl's name is London.

The girl was born from a surrogate mother, just like the couple's son, named Phoenix.

Paris and Carter again kept the birth of their daughter a secret. They did the same with the birth of Phoenix because they wanted to keep the good news private.

"We were very happy and we wanted to tell our family, but we were also very nervous because if you tell someone, this person tells someone else and all of a sudden, it ends up on TMZ or Page Six and I've had enough of that in my life this (situation)," Paris confessed. "So Carter and I made a pact that we wouldn't tell anyone," they said at the time.
