After the public learned about the exciting arrival of Sienna Miller and Tom Sturridge’s little arrival, the couple has finally released new details on the little girl!

According to a report from E!, the 30-year-old actress and her longtime fiancé have named their precious bundle of joy Marlow!

As recently reported by GossipCenter, the couple welcomed their first child into the world this past weekend.

The public learned about the pregnancy back in April when the “Stardust” actress told British Vogue, “Even though I’m under strict instructions not to say anything as it would completely defeat the point of everything I’ve tried to achieve in the last eight years, I’m feeling fine…It’s all progressing nicely and it’s very exciting.”
