Heidi Klum Gives NEW Bodyguard a Shot

Heidi Klum knows ... you can't mix business with pleasure ... and that's probably why she just swapped out the bodyguard she's allegedly fornicating with for a couple of new guys.

Klum arrived to the ABC studios in New York City yesterday -- looking DAMN GOOD -- and accompanied by two brand new security monsters.

As we previously reported, Martin Kristen was guarding Heidi's body as recently as last week ... right before Seal told TMZ they were banging each other.
