Uma Thurman and boyfriend Arpad Busson became parents back in July when Thurman gave birth to a baby girl. But their daughter's name had remained a secret until now.

Today, everyone is talking about this celebrity baby's lengthy name: Rosalind Arusha Arkadina Altalune Florence Thurman-Busson. But her parents call her Luna, reports E! News.

Why so many names?

"Each name has a special reason and meaning to her mother and father," Thurman's rep told E! News.

Thurman isn't the only celebrity who has kept her baby's name a secret. It's a new celebrity trend, reports Parents.com.

Sarah Michelle Gellar and hubby Freddie Prinze Jr. are another celebrity couple who chose to keep the name of their newest child under wraps after his birth late last month.

"How refreshing!" wrote mom blogger Nicole Fabian-Weber on cafemom.com's blog The Stir. "A famous couple not revealing all the intimate details about their child to the world the minute he's born." (Ahem, Snooki, Nick Lachey and company...)

The blogger couldn't resist offering 10 suggestions for what to name the baby Prinze.

And Anna Paquin and Stephen Moyer, who had twins last month, not only refused to release the names of their children, but they declined to release even the twins' genders and date of birth as well.

Here are five more celebrities who bit their tongues when it came to baby's name after giving birth, courtesy of namecandy.com.

What do you think of baby Luna's official name? And do you think keeping a name secret helps to maintain the privacy of a celebrity child?
