Twilight's Nikki Reed and American Idol's Paul McDonald Are Getting Married Tomorrow!

Sources tell E! News the actress and her beau Paul McDonald will wed in Malibu Sunday.

Here comes the bride!

Nikki Reed and former American Idol contestant Paul McDonald are set to tie the knot Sunday at a private ceremony in Malibu, sources told E! News exclusively.

And tonight, the lovebirds (who have been keeping mum on specific wedding details) will kick off the occasion with a rehearsal dinner in Los Angeles. 

Friends and family of both stars arrived in town last night, including members of McDonald's Nashville-based band, The Grand Magnolias.

"He's going to play with his band at the reception," a source said. "He's got some surprises for Nikki."

But McDonald won't be the only one crooning after the pair gets hitched.

Fellow tenth season Idol alum Stefano Langone told us Reed asked him to perform at their wedding, as well.  

And while the Twilight star hasn't hinted at what she'll be wearing when she walks down the aisle, Reed did let us in on a little wedding day dish.

Spy Kids star Alexa Vega will serve as her maid of honor and "[the wedding] will be small," the 23-year-old starlet told us just last week. 

Congrats to the couple!
