If marriage proposals make you teary, you might want to set out some tissues next to your remote for tonight’s Real Housewives of Orange County. In Season 8, Episode 17, “Immodest Proposal,” which airs tonight at 9 p.m. on Bravo, Gretchen Rossi decides to take the plunge and ask Slade Smiley to marry her!

The special moment takes place on the roof of a skyscraper (and Slade arrives via an understated helicopter). An engagement party follows — though none of Gretchen’s co-stars make the guest list.

Last episode, Heather Dubrow and husband Terry decided to sell their gorgeous home. Now they have to let the kids know they’re moving.

Just because Vicki Gunvalson wasn’t invited to Gretchen and Slade’s engagement party, it doesn’t mean the OG Housewife won’t find a moment to confront the groom-to-be about some comments he made about her on his radio show. That’s what “Winter Wonderland” parties are for! (And we thought they only had those kind of events in Stars Hollow!)

Something about mimicking a cold environment must bring the ladies back to Canada, because everyone suddenly voices an opinion about Gretchen at the event. Tamra Barney also takes the opportunity to tell her friends she’s finally set a wedding date, and Vicki announces she and Brooks are back together. Sounds like a party you don’t want to miss!
