Heather Rae Young and Tarek El Moussa are completely 'exhausted' following whirlwind wedding: 'Everything was just spectacular'

They finally tied the knot after planning the wedding of their dreams for 14 months.

Heather Rae Young and Tarek El Moussa are 'completely exhausted' following their whirlwind wedding at the exclusive Miramar Rosewood resort in Montecito on Saturday evening among an intimate group of friends and family.

The 40-year-old home renovation enthusiast admitted 'everything was just spectacular' as they said 'I do' in front of 150 guests during an Old Hollywood-themed event last weekend.

'It was just so magical,' she told PEOPLE. 'Better than we even expected it to be. We are exhausted, but so happy at the same time,' Heather said. 

Tarek agreed that their big day was everything and more: 'It felt like it was straight from a movie.'

No detail was too big or too small, but including Tarek's children from his first marriage to ex Christina Haack — daughter Taylor, 11, and son Brayden, six — was a must.

'I walked my mom down the aisle. I was fine. And then the song Shallow comes on, which is one of me and Heather's songs, and I'm going to get Taylor to walk down the aisle, and I just broke down,' Tarek said. 'Taylor, she's my everything, I just got so emotional.'  

Heather stunned in a long-sleeve corset dress from Israeli designer Galia Lahav and clear heels from Amina Muaddi.

'It was magical. She looked so beautiful,' he says of the first moment he saw his now-wife. 'Her hair was perfect. Her makeup was perfect. She had the coolest wedding dress I've ever seen. I was just smiling huge from ear to ear.' 

Heather added: 'He could see me walking from a distance and he blew me a kiss,' she remembers. 'I just focused on him the whole time, and I don't even really remember anything else that was going on.'

The couple recited their personal vows before including Taylor and Brayden at the floral altar.  

'They came up while we were at the altar and stood with us,' Tarek says. 'And that's the first time we were officially, legally a family of four, so that was very special.'

Heather recalled: 'I never knew I could feel love like I have for the kids and for Tarek. They've given me a family. They've opened my heart up so much and made me more patient, and loving and understanding.'

'Being able to share that moment with the kids, and share vows with the kids…. that was probably my favorite part.'
