Dolls Depicting Real People, How is This Legal?

It has been all over the news, a company has been making sex dolls in the likeness of real life people--celebrities including Justin Bieber and Miley Cyrus. While the look-alike dolls are given a slightly different name, the intent is crystal clear.

Other products like pornography are general sheltered by being works of satire.  But can a static product claim a genre?

And while the gossip has focused on teen idols looking at other listings in the celebrity section include Hillary Clinton and Mariah Carey.

I am guessing the actual product would be a disappointment to anyone wanting to actually use it, and he main market s gag gift.  But still...  I am surprised that profiting off  person's identity in this way has not been shut down by a team of lawyers.

In the end any likeness is very slight, so anyone who has a fantasy about a celebrity is going to be better off (so to speak) using their own imagination.
