It is unbelievable folks, but Rob Pattinson and Kristen Stewart may already be yesterday's news.

The web is hopping with stories that Justine Bieber and Miley Cyrus are the new hot couple and that Rob and Kristen are too old anyway.

Even though there is not a shred of evidence that Justin and Miley even know each other well, let alone date, it has already set off a firestorm as a younger generation begins to make its mark.

What has just happened? An actor turning 24 and an actress still in her teens are already out of the loop and over the top?

That is the true madness of the Internet, where everything has to be the latest, youngest, coolest and hippest.

By those standards, Rob and Kristen, who have been on the radar screen for over a year, are old news.

Sad, but true folks.

Here is what one website just wrote about Miley and Justin:

“How we wish that Miley and Justin hook up with each other. Even though they might not be a fan of each other’s music, but we are sure that their common passion for music would make their bond stronger with each passing day."

Oh dear, this kind of stuff is going nowhere good.

Dublin's shoppers didn't recognize Miley when she strolled through the streets yesterday.
