Cue the wedding bells for one of the "Dancing with the Stars" favorites, Witney Carson.

The 21-year-old pro is now engaged to her longtime love Carson McAllister, 23, according to a report from E! Online.

The "Dancing with the Stars" personality announced the happy news on Instagram, posting a photo of her and her new fiancé at the beach last Saturday.

"My love of four years @carson.mcallister proposed last night & I feel like the luckiest, happiest woman in the world," she wrote in a caption for the beautiful photo. "It was perfect, he's perfect #engaged."

The cute couple has been together for four years, both hailing from American Fork, Utah. The blonde beauty called her future husband her "best friend."

"My high school sweetheart popped the question last night in the most perfect, beautiful way," she said in an interview with People. "He was waiting for me on the beach surrounded by candles. Danced with me while the sun went down and then knelt down on one knee and asked me to marry him! Of course I said yes."

Showing that he's totally in tune with his soon-to-be wife, McAllister also took went to Instagram to post an announcement about their engagement with the sweet caption, "Couldn't be any happier to spend forever with my best friend."

Everything is smooth sailing for the happy couple, but a few months ago, Carson sparked romance rumors with her former "Dancing with the Stars" partner Chris Soules. The chemistry between the two partners fired speculation on their relationship beyond the dance floor.

A report from OK! Magazine even said the pro dancer was the reason behind Soules' breakup with then-fiancé Whitney Bischoff.

"Chris refused to quit speaking to Witney after the show ended," a source revealed in the interview with OK! Magazine last August. The report said the amiable relationship between the partners did not sit well with the "Bachelor" star's ex-girlfriend. "And his relationship with Whitney imploded."

Eventually, Carson debunked the speculation and she was not in the market as she's still dating her high school boyfriend Mcallister. The reality star and her love often post sweet photos on Instagram of their adventures.

According to a report from Wet Paint, the couple has been spending some time apart after Carson pursued her dance career in Los Angeles and McAllister left the country to fulfil a Mormon mission. He spent over a year overseas and came back last May, reuniting with his lady love.
