Filming in the outfit, and with the same bruises, fans have seen his character wear in the first teaser video for the new season, David began: ‘What’s up everybody, how’s it going? 

‘I haven’t done an Instagram live in a little while I think I’ll only be here for like three and a half minutes because I think I have to go set fairly soon. 

‘What’s going on? I’m here shooting season four of our television show. I don’t think I’m supposed to be showing you this.’

He then joked: ‘Who wants to hear some spoilers for season four? Let me just read directly from the script, that’ll be good! It’s a very tough day today, very tough day. I’m exhausted.’

‘I’m just going to read your sections of the script Millie, just going to tell everybody what happens to eleven this season. 

‘”I just told them”, what have you just told them? Oh did you do an Instagram live and you just told them? Dude, why don’t you… make a phone call and see if someone is going to pick up.’

Millie then appeared on the screen alongside him, and asked what he was doing to which he said: ‘I don’t know I’m so crazy, I’m so crazy I shouldn’t be doing this.’
