Lou Pucci, the famous guitarist, and his son, actor Lou Taylor Pucci who has starred in Green Day's Jesus of Suburbia music video and such films as "Thumbsucker" with Benjamin Bratt and "The Chumbscrubber" with Glenn Close. I'm lucky to be friends with him. :)
The thing about this name is that it's pronounced the same way as Loo, which is a British word for bathroom. I use the word Loo (despite not being British), and that's why I wouldn't use Lou as a name.
A nice name, but I would probably spell it Lu rather than Lou, partially because it comes from my favourite cartoon, 'Mike, Lu, & Og', and partially because Lou is short for Louis.
Since I am planning on naming my daughter Louise, I find Lou to be a very safe nickname and is easy to catch on to when your young, so I might introduce her as Lou in the future.
I don't know what Heidi Klum was thinking. Lou is dumb, especially as a legal name on a girl. It sounds too redneck and masculine to be a girls' name. It's also very old-fashioned. If you want to call your daughter Lou, just name her something like Louise, Lucy, or Luana and then call her Lou for short.
I don't like Lou on a boy, it makes me think of an old man. But on a girl, as a nickname for Louisa, it's so sweet. I really like masculine nick-names on girls, Lou is one of the best.
This name has grown on me for both genders. I think it's really cute for a boy, and its kind of edgy but sweet for a girl. I was interested to find it was so popular in France for girls. I would love to meet a little girl (or boy) named Lou!
