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?"
The Christina on the Coast star recently had to share a health update after having to defend her own weight.
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.
