Perhaps it's time to call her Lady Luck instead of The Duchess. Fergie, whose engagement to Las Vegas sex symbol Josh Duhamel was confirmed Wednesday, sure is feeling that way, she tells PEOPLE. "I feel like the luckiest girl in the world," the Black Eyed Peas singer, 32, said Saturday night after a performance at Atlantic City's Borgata Hotel Casino & Spa. "I'm thrilled." During her two-hour show, Fergie gave an adoring shout-out before she performed "All That I Got." "This song is about loving someone for their inner beauty," she told the crowd as her diamond sparkled. "I hope you all have someone like that in your lives. I do." News of the couple's engagement – they have been an item for three years – broke on Christmas Day. Yet when it comes to the specifics of how the question was popped, the "Big Girls Don't Cry" vocalist's lips are sealed. Details Kept Private "I'm not giving any details. I think [the fine points] are sacred," Fergie (real name: Stacy Ann Ferguson) explained on the red carpet outside club mur.mur, where she hosted an after-party. "It's just important to us." Apparently big girls don't dish, either. Then again, Fergie told PEOPLE, keeping quiet is a new challenge. "It's hard for me because I have a big mouth," she said with a laugh. What she did divulge are her plans for the New Year. "In 2008, I just want to have a balance," she said. "I've been touring for about four-and-a-half years straight. So for me, I love when I get to go home now and see my dogs." And not just them. "It's important for me to see more of my family, see more of my sister, my mom and dad," she added.
