Details of Jennifer Lopez’s 50th birthday bash revealed

Jennifer Lopez — who turned 50 on Wednesday — will celebrate her big 5-0 with 250 guests in Miami at Emilio and Gloria Estefan’s house on Star Island, Page Six has exclusively learned.

“There are two homes. One is where they live, and the other is a guest house where they like to throw parties. It’s actually next to Puffy’s house,” a source told us. The bash on Wednesday night will be “gold-themed and it’s going to start at 7 p.m.”

Lopez began her 50th with a birthday shout out from fiancé Alex Rodriguez.

“Hi baby girl. I just want to wish you a happy birthday. You have made me feel like every day is my birthday,” he said in a video message.

J.Lo is celebrating the milestone while on her “It’s My Party” tour.

We hear that Miami Mayor Dan Gelber and Vice Mayor and commissioner Michael Gongora will officially declare July 24, 2019, “Jennifer Lopez Day” in Miami Beach, and present her with the Proclamation of the City and keys to the city.
