Jesus Adams Foster (born Jesus Gutierrez) is the son of Ana Gutierrez and the adoptive son of Stef Adams Foster and Lena Adams Foster, the fraternal twin brother of Mariana Foster. He is also the adoptive brother of Brandon Foster, Callie Adams Foster, and Jude Adams Foster.
Both Jesus and Mariana were born on May 17, 1998. Jesus and Mariana's birth mother, Ana, abandoned them for another man and drugs. It is said that they were with her until they were around five years old. Ultimately, they were put into the foster system and remained there until they were adopted by Stef and Lena six years later, after being fostered by them for five years. Jesus and Mariana are very close and even when they disagree, they still love each other.
