Bachelor stars Sean Lowe and Catherine Giudici are getting married tonight, and the wedding is available on live stream.

Lowe proposed to Giudici in Thailand last March after their romance was revealed on television.

The couple are expressing their excitement for their big day on Twitter and Instagram.

On Sunday morning, Lowe wrote on his Twitter, "'All things work together for good to those who love God.' I know this didn't happen by chance. God was there from the beginning."

He also wrote what the couple's first dance will be.

"And for those asking, our first dance will be to One Woman by @rrbchoir."

On Sunday morning, Giudici wrote, "I'm getting married today! Woohooooooo!" On Saturday night, she wrote, "My last night as a Giudici."

The couple will be getting married at the Four Seasons Resort-The Biltomore Santa Barbara.

Giudici posted a picture of a wedding emergency kit on her Instagram. She captioned the photo, "I know this kit will do me a solid the next couple days :) @pinchprovisions #countdownlowedown"

The couple made an appearance on Kimmel on Thursday where Lowe talked about making his vows.

"As a guy, I'm a procrastinator so I'm still fine tuning my vows," Lowe said. "But I'm in the process of writing them."

Kimmel then asked the couple if they would get emotional at the wedding.

"I'm the softie of the two of us," Lowe said. "So I have a feeling I'll probably break down and cry."

"I'll laugh while he cries," Giudici added.
