In November 2005, Berry began dating French-Canadian supermodel Gabriel Aubry, nine years her junior. The couple met at a Versace photoshoot. After six months with Aubry, she stated in an interview, "I'm really happy in my personal life, which is a novelty to me. You know, I'm not the girl that has the best relationships."
At one point, Berry had indicated that she planned to adopt children, but her experience playing a mother in Things We Lost In The Fire opened her mind to the possibility of motherhood. After initially denying rumors, she confirmed in September 2007 that she was three months pregnant. Berry gave birth to a girl named Nahla Ariela Aubry on March 16, 2008, at Cedars-Sinai Medical Center in Los Angeles. Nahla means "honeybee" in Arabic; Ariela is Hebrew for "lion for God". Berry hired security guards after receiving racist threats to her unborn baby from a stalker, who said her child will be "cut into hundreds of pieces".
At one time, Berry indicated that she did not intend to marry again, insisting the couple's life was already complete without the need for a marriage. She stated that she hoped to have a second child right away.Aubry told In Touch magazine, "I'd like Nahla to have a sibling in 2009."On April 30, 2010, it was reported that Berry and Aubry had separated. Several days later, Berry's representative confirmed the relationship had ended, saying, "They have been split for some time, but remain friends and committed parents to their daughter." They worked out a financial and 50/50 custody deal with a family lawyer, but TMZ reported that it was not final. On December 30, 2010, Aubry filed documents with the Los Angeles Superior Court, asking the court to formally recognize his paternity and grant a court order giving he and Berry joint legal and physical custody over their daughter.
