Denise Richards adopts newborn baby girl

Denise Richards has adopted a child, it has been revealed.

A representative for the actress confirmed that she had adopted a newborn baby girl from the US.

Richards's spokesperson told E Online: "Eloise Joni Richards is named after Denise's mum (Joni) and Denise and her daughters Sami and Lola chose the name Eloise.

"Denise and Eloise's big sisters couldn't be happier and feel incredibly blessed."

Richards later thanked Twitter users for their messages of congratulations, writing: "The girls and I are over the moon and so is my dad Grandpa Irv."

The Wild Things actress is mother to two daughters, 7-year-old Sam and 6-year-old Lola, with ex-husband Charlie Sheen. Her own mother Joni passed away in December 2007 following a battle with cancer.

Richards and Sheen reached an agreement for custody of their two daughters following their divorce in 2006. However, a recent attempt by Sheen to secure a new weekend custody arrangement was reportedly declined earlier this year.

Sheen is also father to twins Bob and Max from his marriage to Brooke Mueller.

Richards described her relationship with Sheen as "a beautiful love story" in an interview earlier this week.

She also promised that her forthcoming memoir The Real Girl Next Door will go into detail about "the good stuff" that happened during their four-year marriage.
