The Dancing with the Stars pros got married on Saturday, July 8, in front of 300 guests at Oheka Castle in Long Island, NY, Us Weekly reported.
"It was everything we ever dreamt of," Maksim, 37, told Us of his fairy-tale nuptials that took place at the 127-room estate.
"And the party of the year!" added Peta, 30.
The couple exchanged vows at the castle Maksim dreamed of getting married at since he first moved to the United States. The romantic ceremony reportedly began with their son, six-month-old Shai Aleksander, being carried down the petal-strewn aisle by Peta's mom.
The bride wore a breathtaking ivory Karen Sabag Couture ball gown which featured an off-the-shoulder fitted bodice and a multi-tiered, full-gathered skirt, according to Us. Peta pulled her hair back tightly into a high bun with a sparkly hair piece wrapped around it.
Peta also sweetly wore heels she bought during her first trip to Maksim's native Ukraine when she walked down the aisle to Tchaikovksy's Nutcracker Suite.
"I danced ballet for 16 years, so it's my favorite album," explained Peta, who was accompanied down the aisle by her father.
Maksim looked handsome in an ivory tuxedo jacket and bow tie with traditional black tuxedo pants.
The couple reportedly exchanged vows they wrote themselves during the 40-minute non-denominational ceremony.
For the reception, Peta apparently changed into a tight-fitted white gown made entirely of feathers with a sheer-panel back. Although Peta and Maksim are both professional dancers, their first dance as man and wife was allegedly slow and simple.
The party's decor was cream, black and white, with "so many flowers and candles and crystals everywhere," Peta told People. "I wanted the entire celebration to be super-chic and glamorous. I just wanted it to be just so pure and gorgeous."
Guests reportedly dined on a five-course meal and then danced to the music of a 15-person band.
"I can't speak for every girl, but when you first step onto that runway and see the love of your life at the end of the path waiting for you, I think that's going to be a moment that I've always waited for -- just to see his face," Peta said before living out her dream this past weekend.
