Like plenty of others in Hollywood these days, McKellar made the announcement on social media.
McKellar started her career as the famous child girlfriend on The Wonder Years and was most recently a contestant on Dancing with the Stars. Sveslosky is a partner at at the international law firm, Sheppard, Mullin, Richter & Hampton. McKellar's rep confirmed the news to People.
"Scott and I are thrilled," McKellar said in a statement.
Last year, the actress told ABC News she wasn't planning to jump into anything too quickly. She explained, "I'm really focused on being a good mom and if the dating thing happens, then alright."
McKellar was previously married to Mike Verta and has a son — 3-year-old Draco. Sveslosky also has a child, 10-year-old Hunter, from a previous marriage.
The actress has previously come under fire for her parenting style — including the fact that she breastfed her son until he was almost 3 years old. Back in 2013, she explained attachment parenting to Good Morning America.
"Cuddling, being close, you know, sleeping in the same bed sometimes, wearing him in a sling, long-term breastfeeding — all have to have this closeness," she said. "On the other hand, doing everything your child wants you to do right when they want you to do it is another thing. Spoiling them is completely different."
McKellar told People that she and Sveslosky are planning to marry later this year and added, "We are looking forward to merging our families."
