Denim and Diezel, sons of Tony Braxton

Banjo, son of actress Rachel Griffiths and Andrew Taylor.

Moxie CrimeFighter, daughter of Penn Jillette

Maybe their instructor could be Diva Muffin, daughter of Frank and Gail Zappa.

Check out this list of Celebrity Baby Names.

Note:  While the Guru, long semi-notorious as a Name Dame, Name Gnome or even the pompous — Name Generator — agrees that names should instantly telegraph a strong positive feeling and even a smile,  she also believes names should not trigger problems in the proverbial sandbox. (Even the corporate sandbox. Wakoopa anyone?)  Of course, these offspring will likely travel with pricey bench-pressing bodyguards to ward off playground bullies.  Civilians should stick with Ava and Abigail (2007 most popular girl names) or Aiden and Braden (2007 most popular boy names). They’re also more apt to fit neatly into all those teeny-tiny squares on the SAT registration forms.
