-- Danica McKellar couldn't be happier as she prepares for a wedding she says "perhaps" could happen later this year.
The "Dancing with the Stars" and "Wonder Years" star, 39, told ABC News that after getting engaged to Scott Sveslosky in July, she wants a small, intimate affair to celebrate their love.
"Wedding planning has been underway for a while," she said, adding that "perhaps" this year she'll be sharing pictures from it on social media. "It will be a really small wedding, because we've both been married before, we've both had big weddings and this time around it's really just about us."
Will her old friends from the "Wonder Years" be there to celebrate with her?
"Like I said, It's going to be a very, very small wedding," she said, laughing. "It's going to be only family, actually. It's going to be really special, because it's just about the two of us. It's not about the production, it's not about the wedding with a capital W. It's about a celebration of us."
McKellar added that her son Draco, 4, from her first marriage would be involved, but she didn't say how.
What she would share was that wedding dress shopping has been "easier 'cause everything looks good," after doing a show like "Dancing with the Stars."
"Getting in the best shape of your at 39 is amazing. I've been keeping it up pretty well," she said after the show ended earlier this year.
She's also "been doing Pilates twice a week with a trainer, which I've never done before and I love it."
"It's also diet, I eat really well. I eat really, really healthy food," she said. "I don't drink soda, I don't drink coffee. I barely drink alcohol, I only drink water. I'm very paleo, very little processed food, I try to eat a lot of raw stuff. I'm not a vegetarian, but I eat very clean meat. I don't eat sugar and white bread ... like anything else, you are what you eat."
McKellar spoke to ABC News on behalf of Colgate's “Smile for Picture Day,” something dear to her heart, especially as she raises a son and teaches him proper dental hygiene.
McKellar shared her tips with on getting the best photos -- including visiting the dentist twice a year and even bringing a little toy or stuffed animal to the dentist so your child has fun, brushing together with your child, playing games and apps that help to "trick" your child into enjoying brushing his or her teeth, and practicing taking pictures before the actual day.
"Sit them down and act like you are taking a school picture," she said of practice. "[Also] give them something funny to think about when the photographer takes their picture."
She continued, "Everything educational can be a game ... it should be fun, should all be games. You want to make sure they develop a love of learning ... why not make things fun for your entire life. teaches him addition, math with games."
