Turns out Nick Cannon may have been a decoy for Amber Rose ... because it seems the real Nick of her desire is Simmons.
Yep, you heard it right. The son of rock god Gene Simmons has just scored the rebound of the year.
Our spies at Playhouse in Hollywood caught Amber and Nick grinding it out ... leaving the club arm-in-arm.
There were signs ... you may remember last week they went to a restaurant together but there was no overt signs of affection.
So Amber's jam is a 6-foot-7 white dude who probably has a big tongue.
Now we get it.
