After a 28-year hiatus post-TV gig, the brother-and-sister duo, who still bicker and tease each other like teenage siblings, now turn out 500 consecutive "Donny & Marie" shows at the Flamingo Las Vegas like it's nothing (here's to at least 500 more!). When she's not recording new albums (she's got 27 and counting; new release with Donny coming May 3), she is writing books ("Behind the Smile," which is about her struggle with postpartum depression, and "Might As Well Laugh About It Now" both made the New York Times best-seller list), retooling her show (new director Richard Jay-Alexander promises exciting changes come May 17), or is wrangling her seven children.

Here, Marie shares some of her favorite things in Las Vegas:

What are some of your favorite places to shop in Las Vegas?
Fashion Show Mall is just like its name. It's like being at the best fashion show for everything: clothes, jewelry, shoes, electronics, cosmetics, home décor. You name it, you can find it there.

Where do you like to dine?
My current favorite is Osterio del Circo at the Bellagio. The best Tuscan-style food, fountain view from the windows, colorful atmosphere -- what's not to like?

Do you have any favorite clubs you like to go to?
I work most nights and am up early in the morning with my children. So ... my favorite lounge is my family-room sofa, curled up with my kids. However, I do try to see all the other shows in Vegas on my nights off whenever I can.

What's your favorite place off the Strip?
The Hoover Dam Bypass is a pretty cool representation of human ingenuity!
