Sean Lowe
and Catherine Guidici are newlyweds!

"The Bachelor" and his leading lady tied the knot during a live televised wedding on Sunday night at the Four Seasons Resort The Biltmore in Santa Barbara, Calif.

Catherine looked stunning on her big day, donning a fitted lace gown with a dazzling diamond belt. She swept her long brunette locks back into a loose updo, adding a delicate veil. Sean looked handsome in a traditional black tux and matching bowtie.

This marks the first live wedding and fourth televised wedding in "Bachelor" franchise history, following the nuptials of Ryan and Trista Sutter, Jason and Molly Mesnick and J.P. and Ashley Rosenblaum

There will be another first for the couple tonight!

They revealed that they've abstained from sex until marriage ... and "Extra's" Mario Lopez put the reality stars in the hot seat before their big day.

"So are you concerned about any performance anxiety?" Mario asked Sean.

"The first time … who knows how long it's going to happen. But, give me 15 minutes, I'll give it another shot," Lowe said with a laugh. 

Hopefully, he won't have any post wedding jitters!
