Selena Gomez shocked the world today by revealing she secretly underwent a kidney transplant earlier this summer after a long battle with Lupus.

And as the 25-year-old “Slow Down” singer continues on the road to recovery, Breaking Celebrity News has exclusively learned she was forced to face another battle – against her destructive behavior.

“Selena must completely avoid drugs and alcohol, and has to live by a new set of rules now,” a family insider said.

“She was given a second chance at life, and wants to live as long as possible. But she knew that she had to change just about everything, especially bad habits.”

As Breaking Celebrity News exclusively reported, Gomez checked into rehab at least twice: once in 2014, and another time last year.

So why did Gomez wait so long to share the news with her fans?

According to the source, “She wanted to be sure that she was in the clear and that her new kidney was functioning properly."
