Nikki Reed said yes to one beautiful dress!

The 23-year-old Twilight star said "I do" to Paul McDonald, 27, on Sunday at a private Malibu ranch wearing a stunning Tacori gown with a 72-inch train.. "It was so feminine," she tells the new Us Weekly -- on stands Friday -- of her strapless frock.

Reed and McDonald, an American Idol season 10 contestant, wanted their celebration to feel "like an outdoor music festival."

Among the 130 guests at the wedding were Reed's best pal and her man of honor DJ Qualls and actress Nia Vardalos.
