Halle Berry's newborn baby girl is being welcomed into the world with a big party, it has been reported.

Berry and French Canadian model boyfriend Gabriel Aubry are "doing great" after the birth of their first child on Sunday, who they are naming Nahla Ariela.

Aubry's sister Eugenie has announced that she is thrilled the baby will be bilingual as 41-year-old Berry is learning French.

"It's been a long time since we've had a new baby in the family," she said. "It's very exciting. My father is so happy right now."

Eugenie added that the family had big party ideas in store for the happy couple.

Donatella Versace has told People magazine that the baby is sure to be "fantastic looking".

The fashion designer explained that she was present at the photo shoot where the couple met and claimed to have made more than a few hints that they should get together.
