Allison Williams stole some of the limelight for herself at the 2014 Vanity Fair Oscar party, but it wasn't because of her dress.

The "Girls" star flaunted her huge diamond engagement ring while she posed for photographers and we couldn't help but stare at the massive bling.

The 25-year-old, who has been dating College Humor co-founded Ricky Van Veen for three years, announced the engagement late February.

Wearing a flowing coral Emilia Wickstead gown with long sleeves, an open back and a high neck, Marnie Allison practically glowed and we can't blame her.

Allison fans better savour her red carpet appearances while they can; the brunette beauty told People magazine that she would give up her career to have children.

Meanwhile, tons of celebs flaunted their gorgeous dresses at the 2014 Oscars:
