The Hills: New Beginnings star posted a flirty bikini pic on her Instagram on Tuesday, but had one fan worried about her well-being.
"Oh Kaitlynn u look too thin r u ok you are so beautiful hope all is ok it was nice to see you healthy for a bit modeling it was normal it seems like the new norm is being shown as super thin is only exceptional," a fan commented.
It's been a couple of up and down months for the reality star. In a joint statement given to ET in early August, Carter and Jenner's reps confirmed they had separated.
"Brody Jenner and Kaitlynn Carter have decided to amicably separate. They love and respect one another, and know that this is the best decision for their relationship moving forward," the statement read.
