The reality star and model was in a relationship with fashion designer Marc many years ago, but now he's married and splits his time between the UK and US.
Ahead of last night's launch show, the A-List: New York star said: "I don't want to be known as Marc Jacobs' ex-boyfriend. I want to be known as someone who stands on their own independently from that.
"Obviously it comes up because he is one of the world's most famous fashion designers. I was 21 years old, and I drank too much I said some stupid things but it gave me this public profile that I was able to do some really good things with and I am very proud of what I have done since then."
Austin seemed a bit surprised that he was booed by the crowd heading into the house, saying he thought they'd be on his side as he is married to a Brit and lives up north. He promised that he'll show everyone in the house that he loves Britain and he'll try to win them over.
