Allison Williams made an entrance at the Vanity Fair Oscars party in LA on Sunday night in a bright pink gown. But it wasn't the colorful look that had heads turning — it was the sparkler on her left hand! Allison announced her engagement to CollegeHumor cofounder Ricky Van Veen just a few days ago, and this is the first we're seeing of the diamond that he proposed with. Looks like Allison is in the right place to celebrate the Oscars and her upcoming nuptials!
