This is the real deal. Desiree Hartsock has officially tied the knot with her fiancé and "Bachelorette" Season 9 winner Chris Siegfried.

On Sunday, the couple exchanged their wedding vows in a romantic Palos Verdes, Calif., church ceremony.

Siegfried eve  shared the good news on Monday when he tweeted, "Guess what?! We're married! #NoJoke #RealDeal."

An E! News insider dished that Hartsock and her mortgage banker fiancé were very excited to finally seal their romance with wedding bands.

"They were so excited to get married. They didn't want to wait another day," the insider said. 

"When Chris first saw Des walking down the aisle he was amazed at how beautiful she was. The ceremony was very emotional and sweet. They kept it very short and they walked out holding hands and kissing," the insider added.

Sources say the intimate ceremony lasted for 15 minutes and when it was over the bride and groom happily rode the Redondo Beach Historic Library and headed to the reception, Aceshowbiz has learned.

Singer Matt White graced the reception by singing "Love and Affection" for the couple's first dance.

It can be noted that Siegfried played the same song to surprise Hartsock during their date in Germany while they were still on ABC's reality dating series.

"She was in shock," a guest told People of Siegfried's wedding surprise for his wife. "Everybody was crying."

"Chris and Des seemed so happy," another guest said. "They were genuinely sweet. She teared up, he teared up. They are just nice people - so normal. It's a shock they met on TV."

"Bachelor" alums Ali Fedotowsky and Brooks Forester were in attendance. Tasks Hernandez, who was one of the contenders for Andi Doorman's heart in Season 10 was also there to serve as the DJ at the reception.

Siegfried reportedly popped the question with a Neil Lane sparkler in the finale of Hartsock's season in August 2013.
