Congratulations are in order to the happy couple!

E! Online is reporting that Twilight beauty Nikki Reed and American Idol vet Paul McDonald (he of the blindingly white smile and unusual pipes) are set to wed today, Sunday, October 16, at an intimate ceremony in Malibu. In keeping with Paul's Idol roots, though, there will be a special guest at the event — friend and fellow Idol Season 10 alumnus Stefano Langone will be serenading the couple at the reception. How romantic!

Paul himself will also be taking the stage with his band, The Grand Magnolias, as a special surprise to Nikki — which is sweet, but dude, can't you take one day off from being a rock star? (We guess the music is just in his bones!)

Other guests include Spy Kids actress Alexa Vega, who will be serving as Nikki's maid of honor, and friends and family of both Paul and Nikki. Feeling bummed that your invitation got lost in the mail? Don't take it personally: Nikki said previously that she expected the ceremony to be very small. 

Nikki has always had great taste, so we're sure she'll be dazzling in her wedding gown. We can't wait to see the pictures!
