Scarlett Johansson's mom, Melanie Sloan, has adopted a baby girl from Ethiopia, Us reports.

Sloan missed Scarlett's Iron Man 2 premiere since she was en route to the African country to pick up her daughter, Fenan, who is 19 to 20 months old. Scarlett also has a older brother, Adrian, a twin brother, Hunter, and an older half-brother, Christian, from her father’s first marriage. Finally, a sister for ScarJo!

Due to the volcano ash cloud, Sloan was stranded in Germany for several days while traveling to Ethiopia. "The volcano put the whole adoption process in jeopardy due to time constraints," a source says. "But it worked out in the end."

Scarlett, 25, and husband Ryan Reynolds, 33, may soon be following in Sloan's footsteps.

"I have every intention of adopting at some time," Reynolds - whose older brother is adopted - said last summer. "I'm very grateful for having my brother in my life. I couldn't be more pro-adoption. There are plenty of kids in the world that need it."
