The insider added, "He didn't want to propose in a public setting, even though there are so many beautiful spots on the hotel grounds that have spectacular views and are well-known as places where people pop the question. But Joe said he didn't want to risk anyone walking by and witnessing it, and he didn't want to tip off Sofia by having security there shooing people away."

Meanwhile, Vergara's ex-fiance Nick Loeb had a few words to say about her engagement news.

According to the New York Daily News on Tuesday, Loeb, who was in an on-again, off-again relationship with Vergara for several years, said, "She is beautiful and majestic and therefore to be loved. Beyond all else in life she deserves happiness, the kind that only true love can bring."
