Another “Bachelor” couple is headed for the altar.

“Bachelor in Paradise” alum Ashley Iaconetti and Jared Haibon got engaged Sunday while filming the show’s fifth season in Mexico, People confirmed.

“I didn’t even tell my grandma yet …” Iaconetti, 30, posted Monday on Twitter, along with a ring emoji.

Friends for several years, Iaconetti, who appeared on Season 19 of “The Bachelor” in 2015, long harbored a crush on Haibon, 29, who vied for “Bachelorette” Kaitlyn Bristowe’s heart three years ago. Their friendship took a romantic turn earlier this year.

Viewers will see the proposal on “Bachelor in Paradise” later this summer.

“I think we just both see each other as lifelong partners, so it’s not scary, for me personally, to call her my future wife,” Haibon told People.
