Michelle Williams, husband Phil Elverum split

Actress Michelle Williams and her husband Phil Elverum, an indie musician, have reportedly separated after less than a year of marriage.

Williams, 38, and Elverum, 40, quietly married and moved in together last summer. The news comes after Williams was seen without a wedding band during her last two public outings.

"Michelle and Phil separated at the beginning of the year. It was an amicable spilt and they remain friends," a source told people.com.

The "Fosse/Verdon" actress first revealed their romance in a cover story for Vanity Fair last July, when she confirmed her marriage to Elverum for the first time. Williams and Elverum got married in a small ceremony in the Adirondacks with a few friends and their daughters present. 

Williams is mother to 12-year-old Matilda with the late Heath Ledger; Elverum has a three-year-old daughter from his first marriage.IANS
