Drama could be brewing in the divorce process of Armie Hammer and Elizabeth Chambers over a difference in the length of their marriage.

The 33-year-old Call Me By Your Name actor tied-the-knot with 37-year-old TV star Elizabeth in 2010 – however the star couple are squabbling over how long they have been together.

TMZ reports that the pair failed to sign a prenup before they swapped vows – and suggest they have been wed for either 10 years, or just under, depending on whose version of events are to be believed.

On Friday, Armie stunned fans when he shared a youthful throwback image of him and his soon-to-be ex-wife on Instagram along with the shock announcement they are filing for divorce.

The Hollywood hunk wrote: “Thirteen years as best friends, soulmates, partners and then parents.

“It has been an incredible journey, but together, we’ve decided to turn the page and move on from our marriage.

“As we enter into this next chapter, our children and relationship as co-parents and dear friends will remain our priority.”

A discrepancy on split dates could impact how much spousal support Armie will be required to pay by law

He added: “We understand this news lends itself to public dialogue, but in the interest of our children and our family, we’re asking for privacy, compassion and love during this time.”

However, speculation has swirled over varying statements about their break up dates.

According to TMZ, Armie has listed January as when they split, while Elizabeth is reported to be stating July.

However, back in May she shared a public post stating: "TEN years married, twelve together, thirteen years as best friends. Happy Anniversary, my love. I’m beyond grateful for you, this decade, our family and the dreamiest Friday night anniversary sunset."

It is suggested that the emphasis on "ten" in the statement suggests they didn't officially say "I do" to each other until May.

Issues could arrive if courts find the couple had been together for less than 10 years as that could impact the degree of spousal support Armie could be legally enforced to pay.

Mirror Online have contacted representatives of both parties for clarification.

Armie and Elizabeth married in 2010 and have two children together – a five-year-old daughter named Harper and a three-year-old son named Ford.
