How very rude... Put it this way, can you imagine David Letterman asking Cameron Diaz, or Jennifer Lawrence what weight they were during an interview? *SWOONS*

Hence why Chris is quite coy in his answering, saying he weighed somewhere between "one quarter of a tonne" and "113lb - and four pounds of that was spray tan."

For those of you with shirtless scenes coming up, you'll need to get cracking with the "airbrushing" (grab the missus's bronzer and blusher brush, she won't mind) and the "sit ups."

For those of you who want to familiarise yourself with Chris before and after his transformation, make your way here...
