There's a new addition to the Lopez family. This time, it's Jennifer's sister Lynda Lopez who has welcomed her first child.
Lynda, 37, a weekend anchor at My9 News in New York City, gave birth to daughter Lucie Wren Lopez Goldfried on Aug. 28, sources tell PEOPLE. Dad is boyfriend Adam Goldfried.
"The baby is really beautiful, and Mommy, Daddy and baby are healthy and happy and doing great," a friend of Lynda's tells PEOPLE.
The journalist's famous sister became a first-time mom
in February this year with the arrival of twins Max and Emme with husband, Marc Anthony.
Prior to joining My9 News in 2006, Lynda hosted the beauty-themed series Glow
on E! Entertainment's Style Network and worked as an entertainment correspondent for such networks as VH1, CBS and NBC.
