Nikki Reed can't stop staring at her engagement ring.

The 26-year-old actress, who got engaged Ian Somerhalder last month after just six months of dating, thinks her flower-shaped diamond is ''the most beautiful thing'' she's ever seen.

She said: ''It's so gorgeous, and I'm very lucky for many reasons, but I look at it every day and just think, 'Wow.' I don't even know what to say. Is that not the most beautiful thing you've ever seen in your whole life?''

The 'Twilight Saga' star, whose divorce from ex-husband Paul McDonald was finalised in late December following their split last May, hinted her family were present when the 'Vampire Diaries' star, 36, proposed, but is eager to keep the intimate details a secret.

She told ''You've got to keep some things to yourself and have a moment. Love is love, and people see it, and they feel it, and everyone's really attracted to that idea. As much as we want to expose as much of that as we can, we also just really want to keep some things for us and our family. You don't have the opportunity to do that very much with what we do for a living, so we're going to do our best.''
