The British Royal Family is definitely the subject of varying opinions as to whether we say the brocha for seeing a royal person. I certainly hope for the best for the baby and the entire royal family. That’s my point of view as a Jew.
However, as to the tabloid coverage, these are publications that have absolutely no intellectual content, and with the exception of some technicalities are no better than pornography. At the very least, they get into discussions as to the personal lives of “celebrities” that are nobody’s business. So as to their coverage of the Royal Family and the expected baby, I have absolutely no interest whatsoever.
