Nikki Reed, Paul McDonald Are Engaged

'Twilight' star and 'American Idol' finalist appeared together at MTV Movie Awards.

They sure looked the part of the happy couple on Sunday night at the 2011 MTV Movie Awards, but what the world found out before "Twilight" took the night's top awards is that star Nikki Reed and "American Idol" finalist Paul McDonald have reportedly made it official.

After less than two months of dating, Reed was sporting a sparkling engagement ring on the red carpet, and a source reportedly confirmed that the pair are going to take the plunge. "He's the one. He's the one," Reed, 23, said of the bearded Nashville singer who came in eighth place on the show this year, according to E! Online.

When McDonald was eliminated from "Idol" in April, he admitted they were an item, calling Reed "super-cool" and saying that she'd been very supportive of his musical ambitions. Us Weekly reported two weeks ago that the pair had shacked up at Reed's Los Angeles home and that she has been trying to help him land a recording contract.

While Reed was hush-hush about her own impending nuptials on the red carpet at the Movie Awards, she did weigh in on the eagerly anticipated wedding in the upcoming "The Twilight Saga: Breaking Dawn - Part 1."

"It was beautiful," said co-star Jackson Rathbone.

"It was stunning; it was like a dream," added Reed, who admitted that she was napping in her trailer when paparazzi helicopters buzzed the set during the shoot to get a peek at the fictional wedding.

E! Online, which first broke the engagement story, quoted Reed as saying that McDonald has been writing a bunch of songs dedicated to her and that he's planning on releasing a "Nikki Reed EP."
