over the weekend to share a new photo with her man as they enjoyed a day at Dana Point beach.
The TV personality sat with her legs draped over Josh as the pair posed in front of a beautiful ocean-front view.
Christina showed off her toned physique in a white bikini and black sunglasses as her newest love interest wrapped his arms around her in a sweet embrace.
The mother of three captioned her post: "Building life together and enjoying some alone time. Love you Josh."
However, fans were more concerned about a shiny piece of jewelry sitting on her fourth finger.
Upon further inspection, Christina seemed to be wearing a wedding band, inciting fan rumors that a secret ceremony took place.
"I see a ring," one gushed in the comments with five heart-eye emojis.
"I feel like you guys are married already! If so, congrats. I love you guys together. Such a gorgeous couple," a second remarked.
A third speculated: "The date is noted in the caption.. white bikini.. maybe we should be congratulating you guys!!!!"
"Looks like an elopement…aka white swimsuit," another reasoned.
"Congratulations I’m guessing are in order!" a final pressed.
MOVING ON
Christina's potential elopement followed her ex-husband Tarek's marriage to Selling Sunset's Heather Rae Young in October.
According to People, the real estate investor and his new wife Heather, 34, couldn't keep their eyes off each other as they prepared for their big day in Santa Barbara.
Heather told the site: "We're best friends, we're true soulmates, and our love is so rare and so special."
She continued: "It's the love I've always dreamed of my whole life."
Tarek shared with the outlet: "I'm just excited to live this life with her. We've got the two babies, we have a family, and we have a very bright future."
During the wedding, Heather wore a fitted corset dress that was custom-made by Israeli designer Galia Lahay.
Tarek had on a black velvet tuxedo with a skull-and-cross bone-print lining.
The TV star and Christina's two kids: daughter Taylor, 11, and son Brayden, 6, were also in attendance at the wedding.
HAPPILY EVER AFTER?
Meanwhile, Christina also firmly moved on by getting engaged to Joshua three years after she finalized her divorce from Tarek.
The new couple announced the news in September, with three photos of the couple as she flashed a large diamond on her left hand.
Right before their engagement, it was revealed that Joshua left his ex-wife "heartbroken" by moving on with Christina just two months after their divorce.
It has been claimed that the HGTV star had been dating the Texas-bred real estate agent for a few months before they were spotted together publicly.
Christina also has a two-year-old son Hudson with British host Ant Anstead, 42, who is said to be dating actress Renee Zellweger, 52.
