Ashlee Simpson is remaining tight-lipped about the intimate details of her engagement to Fall Out Boy star Pete Wentz.

The songstress was happy to share her good news with their fans, revealing that they plan to marry on Pete's website last week.

Simpson, 23, and Wentz, 28, said they wanted their fans to be the first ones to know about the news.

"We know there has been a lot of speculation recently about Pete and I," said the two in a joint statement posted on FriendsorEnemies.com.

"Yes, we are thrilled to share that we are happily engaged."

However, Ashlee remained coy on Ryan Seacrest's US radio show, saying that she wants to keep the exact details of the proposal "scared".

"But I will tell you it was very thoughtful and he did a great job," she added.

She was, however, happy to show off her "huge" diamond engagement ring.
