During YouTube Q&A last week, she insisted it was Matt's decision to pop the question and confirmed it wasn't rushed because of her pregnancy.

Tammy addressed the issue on Friday after a fan asked if her Ironman beau had proposed just because she was expecting.

Matt answered: 'No, good question but no. I was actually planning the proposal a fair bit before.'
