Romance between Ewan McGregor and his wife of 22 years, Eve Mavrakis, reportedly has bitten the dust. The pair, who share four children together, goes separate ways since May amid reports of the actor kissing his "Fargo" co-star Mary Elizabeth Winstead in London, PEOPLE reports.

On Sunday, October 22, the "Star Wars: Episode II - Attack of the Clones" actor was photographed passionately kissing 32-year-old Winstead at The Good Life Eatery I in St. John's Wood, North West London, according to The Sun. An onlooker told the site, "Ewan Mary Elizabeth were there together and seemed relaxed in each other's company," before adding that "there's always lots of celebrities around in that area."

"They were deep in conversation and were there together for more than an hour. As they left she got on to the back of Ewan's motorbike and they sped off together," the onlooker continued speaking of the two, who stars on the FX series. "The cafe was really busy with people including delivery drivers coming in and out the whole time. You cannot reserve a table in there and have to go to the counter to order food, so people are up and down ­constantly."

Back in February, Winstead took to her Instagram account to share a photo of her and McGregor. She captioned the photo, "Pretty lovely Canadian Sunday. Good Night!" On "Fargo", Winstead plays Nikki Swango, the on-screen lover of McGregor's Ray Stussy.
