Michelle Williams is engaged to Andrew Youmans according to reports. Williams, 37, who recently drew publicity over her payment discrepancy in All the Money in the World, has reportedly been dating the financier, 50, since last July.
Reports of their engagement have surfaced after Williams was seen wearing a heart-shaped diamond ring on her left hand to the Golden Globes and at the beach in the Bahamas on New Year's Day.
Williams, who took the founder of the #MeToo movement, activist Tarana Burke to the Golden Globes, initially dismissed questions at the award show, saying the reason for the ring was because it was a "beautiful piece of jewellery".
The Oscar-nominated actress, who is notoriously private, is yet to comment.
Williams, who has a daughter Matilda, 12, from her relationship with Heath Ledger, has said that for years she was dating just to give Matilda a stable home life, but more recently decided to date just for herself.
Heath Ledger died in New York almost 10 years ago, on January 22, 2008.
Williams has been linked with director Spike Jonez and actor Jason Segel.
