In the video, Bridgette showed off her round diamond engagement ring and was all smiles and giggles.

The traveling ER nurse from Ventura, CA -- who finished in ninth place on Big Brother in 2016 -- often gushes about the man in her life on social media.

"You make me smile so much my face hurts #cheesinfromdusktilldawn #adventurebuds," she captioned a series of photos from couple's July vacation to Catalina Island.

Shortly after Bridgette revealed her big engagement news, many of her fellow Big Brother alums expressed their support and excitement.

"AHHHHHHHHHHHHHHHHHH BRIDGE !!!! CONGRATULATIONS HONEY !!" Da.Vonne Rogers from Season 17 and 18 commented.

Big Brother's fifteenth-season runner-up, GinaMarie Zimmerman, noted, "Congratulations!!!!!!! Woooooo gorgeous girl."

And Season 18 houseguest, Natalie Negrotti, added, "YAYAYAYAYAYAYAYAYYYYYYYY STFUUUUUUUUUU!!!!!! Congrats baby!!!!!!"

As fans probably recall, Natalie and Bridgette were in a "spy girls" alliance together on the show.

Two-time Big Brother runner-up, Paul Abrahamian, also said, "BRIDGETTE CONGRATS OMG!!"
