Baby Mamas! Kristen Stewart and Girlfriend To Adopt Child Together

Kristen Stewart and Alicia Cargile have proven themselves as solid co-parents to their pet pooches, and insiders tell RadarOnline.com that the two are now committed to taking a huge step forward by adopting a baby together!

“This is something they’re completely serious about,” said one pal, noting the pair is “very much in love” and that Stewart’s good friend Sandra Bullock has been helping answer all their questions.

“Sandra has been advising Kristen and Alicia on the adoption process,” revealed the pal. “Right now they’re very interested in adopting a child that’s a little older, no younger than a toddler.”

Stewart, 26, and her visual effects producer girlfriend realize the process could take up to two years, said the friend, but “they can back out at any time, so it’s worth starting as soon as possible” — not that they’re anticipating another split.

“They’re both extremely excited and are already making plans for their change in family dynamic, including house hunting and checking out private schools,” noted the friend. “It’s a very exciting time for the couple.”
