In response to a fan asking if she felt any different being a wife, now, Katie mused that had 'only been 17 days,' but she does love her husband '50X more.'

'I can't explain why!!!! I def feel like I'm entering a new era,' she said.

'Lane and I had our second date at this house and spent most of 2020 here, so it's a special place for us as we built the foundation of our relationship here,' she told People. 

As a couple, the pair have attended 29 weddings together, which made planning their own a bit easier. 

'From going to all these weddings, we learned the most important thing is the energy the bride and groom bring,' Katie said. 'We envisioned a ton of dancing, amazing lighting, good food and stunning decor of course, but the most important thing was to create the loving and magical energy. We wanted our celebration to be filled with joy, not only from us, but everyone attending.' 

For her rehearsal dinner, Katie wore her mom's wedding dress from 1983, which she tailored into a minidress.

Katie walked down the aisle to the track, You Are in Love, by Taylor Swift, in a Dana Harel lace gown. 

Katie also told the outlet that she is 'most excited to start a family and have a partner to go through everything with.'

'We both have so much respect for each other,' she raved. 'We love that we both have the same values in life, and what we want out of this lifetime. We are both so hardworking, yet know the meaning for life is beyond careers. We are so excited to have kids, and enter that chapter of our life as parents.' 

She continued: 'Lane and I are are so fulfilled with not only our wedding, but the life we have created together, and we can’t wait to see what the future has in store.'
