Michelle Williams and her financier boyfriend Andrew Youmans are engaged.
While Williams has denied wearing an engagement ring in recent weeks, Us Weekly says the pair is indeed engaged.
A rep for Williams would not comment on the story.
The notoriously private actress has kept her relationship with Youmans on the down-low since they were first spotted together last July. They have hardly been photographed together and have yet to make a public appearance as a couple.
Williams has a 12-year-old daughter, Matilda, with the late Heath Ledger.
