"Why are the live feeds off....Maybe cause of this....SHE SAID YES!" Schroeder captioned a picture via Twitter. "Thank you sooo much @CBSBigBrother @CBSi #bb16." The reality star got down on bended knee and held Lloyd's hand in the backyard. The soon-to-be spouses were surrounded by the season 16 cast and their closest family and friends.

"I'm engaged!!!!!" Lloyd tweeted at the time. "Celebrating our engagement," she added, alongside a picture of her longtime love out to dinner. ("Big Brother" host Julie Chen hinted to viewers this week that the couple would be returning to the CBS lot for a special surprise.)

Schroeder and Lloyd -- considered by fans to have the best BB showmance of all time -- first met and fell in love on season 11 in 2009. They both competed again in season 13 as part of a duos twist.
