The End of Ka-Boom?

Okay, like I said here...

"Tom Cruise + Katie Holmes = TomKat.
Surely, Kate Bosworth + Orlando Bloom = Ka-Boom. Right?"

So this time, Orlando Bloom is going out with Penelope Cruz and you would get...

Orlando Bloom + Penelope Cruz = Orlando-lope.

They Broke Up?

They broke up? It didn't even really register with me that they were going out with each other. Because if it had, knowing that:

Tom Cruise + Katie Holmes = TomKat.
Surely, Kate Bosworth + Orlando Bloom = Ka-Boom. Right?
