Ashlee Simpson: "I'm a Lucky Girl"

But she opened up about hubby-to-be Pete Wentz.

"I didn't know I'd be getting married right now, but I'm so happy to be!" she said, calling from her mother's Ritz-Carlton hotel room in NYC. "I'm a lucky girl."

How did Wentz pop the question?

"That part I am keeping sacred," she said, "but I will tell you that it was very thoughtful, and he did a great job." "Of course, it was thoughtful," she added, "He's like that."

Simpson — who flashed her new engagement ring (which Wentz designed) in NYC Wednesday — said she loved her rock.

"It's definitely a big diamond!" she said. "I go, 'Oh, my God, I can't believe its on my hand!'"

When asked if she'd be marrying soon, Simpson replied, "I can't tell my secrets," but added, "my mom loves Pete, so does my dad!"

Seacrest avoided asking flat-out if she were pregnant, but asked whether she'd be drinking booze during her stay this week in NYC.

Simpson replied, "Who knows? Maybe."

Ashlee Simpson and fiancé Pete Wentz were spotted in New York City after a dinner-date with Joel Madden and Nicole Richie. The couples were not pictured together, however, Ashlee and Pete were pictured leaving the place. Ashlee showed off her new engagement ring and the newly engaged couple were very cuddly!
