"The turkey ain't the only thing in the oven this year! #grateful #cheers," Sierra wrote alongside an Instagram slideshow of photos featuring the couple cuddling in their kitchen, toasting glasses and eating pie together. "It's sparkling apple cider from here on out!"
"Della Dawn Anglim, our world is forever changed. Thanks for choosing us baby girl. #WelcomeToTheTribe #Noble," Sierra captioned a photo of Della resting on a fur blanket and wearing a cute headband at the time.
And Joe shared the same photo last year and wrote, "There are no words..We are forever grateful for you and can't wait for the most exciting and best season yet. Ms. Della Dawn Anglim..#GodisSoGreat #noble #daughter #precious #light."
Sierra announced her engagement to Joe back in early April 2019 with an Instagram posting while Joe's Survivor: Edge of Extinction season was airing on CBS.
"Forever and ever, amen," Sierra captioned a close-up photo of the couple's hands with a pear-shaped engagement ring on her finger at the time.
Joe, a jewelry designer who has competed on Survivor three times, and Sierra, who has competed on Survivor twice, met when they competed against each other on Survivor: Worlds Apart, the 30th season of the show that aired on CBS in 2014.
However, the couple did not fall in love during Survivor: Worlds Apart -- in fact, Sierra voted Joe out of the game!
Joe attempted to use his flirtatious and charming nature to manipulate Sierra duringSurvivor: Worlds Apart, but Joe told The Salt Lake Tribune in 2019 "she was not having any of that."
"We really didn't even have that great of a relationship, even within the game... She voted me out, which she reminds me of every chance she gets," Joe shared with the newspaper.
According to Joe, the pair's "friendship developed" after the game when they both attended Survivor-related events or gatherings, and then they ultimately met each other's families.
"Neither of us was looking to have a relationship or find love on an island," insisted Joe, who grew up in Arizona but is now living in Utah with Sierra.
"You always say, 'Oh, what if?' But in reality, you know that's not going to happen. And you shouldn't couple up because it's bad for your games [to be viewed as a power pair]. But, again, all this happened after the fact."
Joe said he and Sierra realized how much they had in common as time progressed.
In addition to playing on Survivor: Edge of Extinction and Survivor: Worlds Apart, Joe had appeared on Survivor: Cambodia -- Second Chance, the 31st Survivorseason that was cast based on viewer voting.
As for Sierra, she also returned for Survivor: Game Changers, the franchise's 34th season.
