And Life & Style has all the romantic details inside their gorgeous wedding day.
The pair said “I do” on The Bachelor live special on Jan. 26 at the Four Seasons Resort The Biltmore Santa Barbara.
Wearing a gorgeous strapless Monique Lhuillier mermaid gown (the third dress she tried on), all eyes were on Catherine as she made her way to her hubby-to-be.
So who watched the duo take the next step in their relationship?
Bachelor and Bachelorette stars such as Ali Fedotowsky, Trista and Ryan Sutter, Desiree Hartsock, Chris Siegfried, Jef Holm, JP Rosenbaum, Ashley Hebert, Molly and Jason Mesnick, and, of course, Chris Harrison.
After they said their vows around 6:30 p.m., the reception began and that’s when the party really kicked off.
Everyone looked on as the pair had their first dance to “One Woman” by the Randy Rogers band.
Guests enjoyed an array of delicious food catered by the hotel.
“They had a seated dinner, which consisted of steak, scallops, red and white wine, as well as other snacks,” a guest tells Life & Style.
There was also a beautiful scripture from Genesis 29:30 on the back of the reception placements, which read:
“So Jacob worked seven years to pay for Rachel. But his love for her was so strong it seemed to him but a few days.”
With full bellies, it was time for everyone to crowd the dance floor.
“Everyone danced to songs like ‘Shout’ and ‘Do the Hustle,’ along with some more contemporary sons like Katy Perry’s ‘Teenage Dream,’” adds the eyewitness.
The soiree ended just after midnight.
Even before the day began, the wedding party was killing time with a ton of fun activities.
“Her bridesmaids ate veggies and sipped on mimosas while she got ready,” another onlooker tells the mag.
“Sean played football with his friends on the front lawn of the hotel and took photos with a bunch of fans.
“He greeted his dad and grandmother in the hotel with huge hugs and they told him ‘congrats!’”
As the newlyweds tell Life & Style in this week’s issue, on stands now, they couldn’t wait to tie the knot.
“I’m pretty sure I’ll shed a few tears when I say my vows!” the 30-year-old former bachelor told the mag.
And his bride?
“When I get nervous,” I laugh,” she said, adding, “You never know – I could cry.”
Wedding planner to the stars, Mindy Weiss, oversaw the nuptials (which cost about $250,000!) and made sure it was perfect for the reality TV couple.
“We mixed electric furniture, even brought chandeliers that sat outside in the garden,” she tells Life & Style.
Now that the day is finally over, it also signifies they’ve consummated their marriage – the first time they’ve been intimate since getting engaged in 2012.
“I can’t wait for that moment, after the big day is over,” Sean, who became known as the virgin bachelor, said to Life & Style.
And the brunette beauty, 28, who relied on Pinch Provisions Bridetastic Kit to prep her for Jan. 26, could hardly contain her excitement, telling us days before the wedding, “Oh, yeah, I’m ready!”
This much is certain: they’re in this for the long haul.
“Never in my wildest dreams did I think I would go on a reality show, meet my wife and go on to have a happy life. It’s incredible,” shared the Dallas native.
“As a husband, I will do everything in my power to make her happy.”
