It would just be kind of weird, because shortly before leaving for Canada she was posting all that stuff about a breakup or relationship problems (the tarot cards, ugh), but when she was in Canada she was planning this trip. So if she is with a man they either reconciled quickly OR she picked up someone new already.
Also when she was posting about France while in Canada I assumed she was planning to go with her mom and they were planning together.
Last time her mom came to London in early 2020, Estée also kept it quiet and never said Kelly was there, and they went away together and Estée pretended she was alone. So I kind of was getting the vibe the same thing was happening here.
However, prioritizing a man over her family is very Estée so it would also explain her staying like a week and half in Canada and then jetting back to go to France with a guy lol.
Anyway, she is on Insta nonstop so she definitely likes the speculation.
