Trump says Heidi Klum no longer a 10

Supermodel Heidi Klum is "no longer a 10," according to GOP presidential candidate Donald Trump. 

Oh really?

Klum has fired back.

Klum posted a video on social media of herself ripping off a shirt with '10' on it to reveal a shirt with '9.99' on it as a man with a Trump mask watches.

'Trump' then shrugs his shoulders.
