Click here to see Fergie’s ring!

Back from a vacation in Cabo San Lucas with soon-to-be hubby Josh Duhamel, Fergie was spotted stepping out for a few errands in Brentwood today.

Fergie, 32, proudly showed off a big diamond ring, as she’s still basking in the fact that she’s now an engaged woman.

Of the big news, an insider told People magazine: “Fergie called a lot of her girlfriends to tell them the news. She said they don’t know what kind of wedding they want yet, but that she is the happiest girl on earth.”

The picture isn’t that clear, but what are your thoughts? Who got the better rock- Miss Alba or the Dutchess?
