The petite star, who has two children with Jionni, dressed in traditional white for the ceremony which took place in New Jersey.
And, after becoming famous on a reality TV show, it's no surprise that she kept her fans updated throughout the day.
Posted the first snap on Twitter, she wrote: "Sharing my first photo from my wedding today..."
In it, Snooki - aka Nicole Polizzi - looks demure in a lavish lace dress with a floor length veil... Makes a change from her usual choice of head to foot leopard-print!
She later added the picture fans had been waiting for... Of herself with new husband Jionni.
Alongside the newlyweds together, she said: "I DO! I'm officially MARRIED to Jionni... #nicoleandjionni."
Snooki was quick to tell her fans that they'll be able to watch her "marrying the man of my dreams" on her reality TV show with Jwoww on MTV, Snooki & Jwoww.
Jwoww was one of 15 bridesmaids wearing '20s inspired headpieces and black strapless mermaid gowns.
After sharing a photo of her first kiss as a married couple, Snooki changed into a less formal dress for the reception.
She wrote: "This is my beautiful reception dress that I wore for my first dance as a married couple with Jionni. It is by Ines DiSanto and the style is named Elite. It is also available at www.bridalreflections.com!"
She then shared the picture of their first dance as Mr and Mrs LaValle, describing it as her "princess moment".
She thanked fans for their support when she wrote: "Thank you all for all your messages of love and support! We had a magical ceremony and I can't wait to share more with you soon! Make sure you tune into Snooki and JWOWW on MTV at 10/9c on MTV to see all the precious moments! xoxoxo."
The happy couple got hitched on Saturday (29 November) at St. Rose of Lima Church in East Hanover, followed by a reception at the nearby Venetian banquet hall in Garfield.
Snooki and Jionni, both 27, got engaged in March 2012. The couple moved into their dream home in Morris County in September. They are parents to two-year-old Lorenzo and two-month-old Giovanna.
Congratulations to the newlyweds!
