Carson and Mcallister, 23, are from the same hometown of American Fork, Utah, and the two are so adorable on social media that they could easily steal the #RelationshipGoals crown from Taylor Swift and Calvin Harris.
We mean, seriously.
Mcallister gave a pretty good indication that he might be proposing soon after he posted some sweet pics of himself cuddling up to Carson in Cancun in June.
"Had the best week ever with @witneycarson!" he captioned an Instagram snap taken on the beach in Mexico. "Couldn't imagine a better person to spend it with! Love this cutie!"
When the cute couple officially ties the knot, it may be déjà vu for the DWTS family. Carson was a bridesmaid in fellow dancing pro Lindsay Arnold's June nuptials to her high school sweetheart, Sam Cusick. Coincidentally, Arnold and her beau are also from Utah -- they were raised 30 miles north of Carson and Mcallister in Salt Lake City.
Carson, who is dancing with Carlos PenaVega this season, was a So You Think You Can Dance contestant before joining DWTS. She started in a troupe dance on the ABC competition show in 2013 and became one of the series' pros last year.
Congratulations to the happy couple!
One of Carson's fellow DWTS competitors also has stars in their eyes. Bindi Irwin recently gushed to ET about having the support of her boyfriend, Chandler Powell, as she competes alongside dancing pro Derek Hough for the season 21 mirror ball trophy. Watch the sweet video below.
