"Twilight" star Nikki Reed and her fianc?, former "American Idol" contestant Paul McDonald are expected to tie the knot on Sunday, October 16.
A source told E! News that the couple is having a rehearsal dinner in Los Angeles on Saturday evening and will wed in a private ceremony in Malibu on Sunday.
According to the entertainment site, friends and family arrived on Friday evening from out of town, including McDonald's band members from his Nashville-based band, The Grand Magnolias.
"He's going to play with his band at the reception," the source told E! News. "He's got some surprises for Nikki."
The actress and her aspiring singer beau revealed their engagement in June after dating for about three months.
Reed was spotted with an engagement ring during the 2011 MTV Movie Awards and when she was asked about marrying McDonald, she replied, "He's the one," according to E! Online.
Reed, 23, plays vampire Rosalie Hale in the hit "Twilight" movies, alongside stars Robert Pattinson and Kristen Stewart. She recently filmed scenes for the fourth installment, the two-part "Breaking Dawn." McDonald, 26, was a finalist on "American Idol" season 10.
Reed and McDonald first met when the "American Idol" finalists attended the Hollywood premiere of "Red Riding Hood" in early March.
The couple's meeting was caught on camera as Reed said, "You're amazing. I'm blushing, I should go" before hugging McDonald awkwardly.
When she was out of earshot, McDonald said to the camera, "Was she a famous actress or something? I'd hang out with her!"
McDonald recently said during a radio interview that he hasn't seen any of Reed's movies, saying, "She's super cool, man. I think she likes me more because I've never seen any of her stuff."
