The 33-year-old actress, who has reportedly hired a lawyer following husband Rupert Sanders's affair with actress Kristen Stewart, posted the image without comment on the British fashion bible's website this afternoon (August 20).
It's believed that the British mother-of-two could be set to return to the UK, with a source telling US publication People: "[Ross] has no strong ties in the US nor does she want to remain here.
"She obviously wants them to carry on seeing their father, but she feels there is no point in staying in the US.
"Given that the majority of her family and friends are in the UK, nothing is holding her here and the kids are young enough to start a new school and not be affected."
Ross had also described her recent holiday in Hawaii with her family after the pair's lengthy promotion for Sanders's Snow White movie in an older blog post, saying: "We are getting some R&R on the north shore of O'ahu after a lengthy press tour for Snow White & The Huntsman.
"It's so beautiful here - we are staying in an artist's house right out on a point with waves crashing either side of us."
