A representative for Denise said: "Eloise Joni Richards is named after Denise's mom (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."
The star added on twitter: “Thank you all for your sweet messages. The girls and I are over the moon and so is my dad Grandpa Irv … xo. (sic)”

The actress also changed her profile on the micro-blogging site to read: “Actress, single mom of three adorable daughters, animal lover, some say I'm a good cook, and I'm always up for trying something new.”
Ironically, Denise, Charlie and their children were staying in the Eloise suite at New York’s Plaza Hotel last year when panicked porn star Capri Anderson called police after Charlie – who was drunk and had been taking cocaine – began smashing up his room after accusing Capri of stealing his wallet and cell phone.
Denise and the girls were staying in a separate room.
