Each year, there are celebrities who name their little angels with names that are not usual to ordinary ears. Just like Scott Disick, the long time boyfriend of Kourtney Kardashian, he named their new baby girl as Penelope Scotland Disick.

According to a baby naming expert, the couple did a good job in giving such a name that is both ancient and sexy. Penelope is proof that Kourtney did not use another name that starts with the letter 'K' just like the rest in their family.

It is common for most celebrities to come up with a unique name so as to keep up with the level of 'coolness' of their popularity. Now, it becomes a problem all at the same time when the bar keeps getting raised each year when it comes to celebrity baby names.
