The ceremony was held at the Four Seasons Resort Santa Barbara, and broadcasted live to the country on ABC.
Catherine was stunning in a Monique Lhuillier gown with her hair tied back, and a gorgeous Neil Lane ring to match.
Sean didn't hide his emotion at the altar, opening up the floodgates as he said his vows, "From the moment I met you I wanted more. You had me hooked from the beginning and I didn't want to let you go. We met in the strangest way possible… I know that we met on 'The Bachelor' so that I could fall in love with my best friend… Every day I am encouraged by your love and your selflessness… I'm going to love you for eternity."
Other "Bachelor" stars in attendance included, Trista and Ryan Sutter, Ashley Herbert and J.P. Rosenbaum, Jason and Molly Mesnick, Desiree Hartsock and Chris Siegfried, Juan Pablo Galavis, Arie Luyendyk, Jef Holm, John Wolfner, Charlie Grogan and Danielle McBride.
"Extra" spoke to Sean and Catherine just moments before "The Bachelor Wedding," as they were getting ready to tie the knot. "Extra" also asked Sean and host Chris Harrison about the recent comments from Juan Pablo Galavis about a gay "Bachelor."
The happy couple, who have been open about their decision to abstain from sex until marriage, told "Extra's" Mario Lopez about plans for their wedding night. Lowe said, “The first time… who knows how long it's going to happen but, give me 15 minutes, I'll give it another shot.” Catherine said she is not nervous. “He’s a gentleman.”
