Sienna Miller dazzled during her public appearances at Cannes this weekend, but she definitely had people wondering about the status of her relationship/engagement with Tom Sturridge. MIller was spotted at times wearing her engagement ring. At others it was noticeably absent.

The Daily Mail reports that things aren’t all sunshine and roses for the couple, with Tom Sturridge and Sienna Miller frequently involved in ‘blazing rows.’

The couple has been engaged for about three years.

Sienna Miller arrived at the Cannes Film Festival on Saturday, wearing her engagement ring. The next day, she walked the red carpet without it. On Monday, Sienna Miller took 22-month-old daughter for a walk in her stroller, and wasn’t wearing her engagement ring.

Tom Sturridge, known for his close friendship with Twilight star Robert Pattinson, didn’t join Sienna Miller in Cannes.

A source said of Sturridge and the American Sniper star, “Sienna and Tom are in very different stages of their lives, despite sharing so much together. There are rows about money too, Sienna has a lot of personal wealth and he doesn’t.”

“They are both from well-off families but paying for mortgages and things does come up,” the source added.

Miller played the role of Taya Kyle in the Academy Award-winning film.

Sienna Miller’s previous engagement, to Jude Law, fell apart very publicly. She called it off in 2005 following the revelation that he had had an affair with his children’s nanny Daisy Wright.

Many couples experience financial differences. It isn’t a surefire reason for two people who have been in love for more than three years to go their separate ways.

Sienna Miller served as a jury member at Cannes.
