In a celebratory caption, the Flip or Flop star wrote: "Celebrating the birthday girl @akeith9999 in Napa," alongside two wine glass emojis.
And the friends only added onto their "twinning" status by wearing incredibly similar looks, with Christina in a faux-leather coat, green top and jeans, while her friend opted for a black jumper with jeans and a neck-scarf.
Both of the friends completed their looks with matching sunglasses.
Fans were amazed with how similar the pair looked, and one wrote: "You look twins!" Another quickly agreed, as they added: "Looking like twins."
Fans were convinced the pair were twins
A third fan posted: "You look like sisters," while many others simply wrote that the friends were "twinning."
But one fan was confused by the picture, as they asked: "Who's who?"
Fans were concerned after she shared a selfie from her bathroom, with some saying she looked "sad" and "thin."
The star faces some major health battles
In the health update, Christina – who battles autoimmune diseases – told fans that she was receiving treatment from her doctor to boost her immune system, as well as having a dose of vitamins.
Clapping back at fans concerned over her weight, the star wrote: "So, people are commenting that I look really skinny and I need to eat. This is actually the way that I've always weighed."
She added: "You guys just watched me have babies and then go back to my original weight. Don't worry. Everything is fine."
Christina has always been open about her battles with Hashimoto's thyroid disease and PCOS (polycystic ovary syndrome), as well as skin flare-ups caused by eating certain foods, so she has to completely overhaul her wellness regime.
