Alexa Vega poses with the real Gaby Rodriguez in this behind-the-scenes pic from The Pregnancy Project.

The 23-year-old actress stars as Gaby, an 18-year-old high school student who forces her school and community to confront its prejudices and preconceptions about teen pregnancy — and makes national headlines in the process.

The story begins with Gaby deciding that her senior project will be on stereotyping, which she decides to experience firsthand. Confiding in her mother Juana (Judy Reyes), her boyfriend Jorge (Walter Perez) and a handful of others, Gaby begins her social experiment in which she tells her friends, family and teachers that she is pregnant.

While her fake baby bump continues to grow over the next six-and-a-half months, Gaby carefully records how she is treated and what is being said about her – for better and for worse — both in and out of school.

The Pregnancy Project premieres Saturday, January 28th @ 8PM ET/PT on Lifetime. 15+ pics inside…
