While Disick is not married to Kardashian, with whom he welcomed his third child in December 2014, the pair have not publicly announced any change in their relationship.
Some outlets are speculating that the woman is no mystery to Disick, rather someone from his past: ex-girlfriend Chloe Bartoli. Bartoli and her twin sister Marie-Lou are Hollywood fashionistas who have styled Poppy Delevigne, Miranda Kerr, and Selena Gomez, among others.
Disick is not the twins’ only link to the Kardashian family, however. Another of the Bartolis’ clients, Chrissy Teigen, is close with Kim Kardashian and Kanye West through her husband John Legend. The couples have been on at least one double date, and Teigen and Legend even attended Kimye’s Italian wedding back in May 2014.
