The Modern Family star is marrying her Magic Mike fiance at The Breakers Palm Beach resort after a whirlwind romance, and the actress could not contain her excitement as the wedding approaches.

She posted a photograph of the couple surrounded by red and white roses on Instagram.com on Friday (20Nov15), writing, "We r (sic) almost ready!"

Wedding guests were treated to a private beach bash at the Florida resort on Thursday (19Nov15), and celebrations are expected to continue on Saturday (21Nov15) with a cocktail party.

Sofia's Modern Family co-stars Ariel Winter and Jesse Tyler Ferguson have already been spotted arriving at the resort, and her son Manolo has been posting pictures of the build-up to the big day on Instagram.

Editors at Hello! magazine report the pair has asked their 400 guests to donate to charities - including St. Jude's Children's Hospital - instead of buying gifts. Sofia is a celebrity ambassador for the charity, which aims to treat and defeat childhood cancer and other life-threatening diseases.

Sofia and Joe met in July, 2014, and they became engaged just six months later during a trip to Hawaii. It is the Colombian star's second trip down the aisle - her first marriage to Joe Gonzalez, father of her son Manolo, crumbled after just two years in 1993.
