Paris Hilton is now Paris Hilton-Reum.

The TV personality and entrepreneur married her boyfriend, Carter Reum, on Thursday in Los Angeles, she confirmed in a blog post Friday.

Calling it "the best day and night of my life," Hilton, who wore a gown by Oscar de la Renta, gushed that walking down the aisle toward Reum was "pure magic."

"I finally got to kiss my Prince and begin the happily ever after I've been dreaming of since I was a little girl," she wrote. "It was a true fairytale wedding."

Hilton and Reum, both 40 years old, announced their engagement in February. In her post, Hilton wrote that Reum, a venture capitalist, is her "equal" and "someone who wasn't fascinated with 'Paris Hilton.'" In the hours leading up to their wedding, Hilton sipped champagne and took photos with her bridal party, including her matron of honor, sister Nicky Hilton Rothschild. After a "first look" with Reum ("It was a Cinderella moment and I knew I found my true love"), Hilton walked down the aisle to her friend, singer Kim Petras, crooning "Can't Help Falling in Love."

"Getting to see the faces of all my loved ones, and closest friends out in the crowd, and all their eyes on me I felt more like a Princess than ever before. Then seeing Carter's handsome face... It was almost more emotional than the first look. I had to hold myself together though because if I didn't then I'd be crying in all the footage for the show. It was such pure magic," she wrote. "I reached the end of the altar and Carter took my hands in his. Suddenly I wasn't as nervous. Carter has that effect on me... he makes everything feel like a fairy tale."

"The exchanging of our vows, and then our 'I do's' were definitely a dream. I finally became a wife to the most charming Prince!" she added.

Afterward, the newlyweds had their first dance at their reception as Demi Lovato performed "I Will Always Love You." Calling the celebration "everything I wanted," Hilton noted that she and Reum enjoyed special dances with their father and mother, respectively, and laughed at speeches by their siblings.

"We ended the night with dancing and raging to a DJ set," Hilton wrote. "If I could do it all again I would in a heartbeat. I was incredibly happy being surrounded by so many loved ones and for everyone to be catching up and letting loose and celebrating."
