When Emma and Willis renewed their vows for their 10-year wedding anniversary, the pair "wouldn't do it" without Demi there.

I have so much respect for how Bruce and Demi worked through their divorce to be able to put their children first. I learned so much from that and grew so much from watching that. It was important for her to be there. She was at our first wedding. I loved having her there again. I wouldn’t do it without her."
