Laura Prepon sparked short-lived wedding rumors when she was seen being privately fitted for a white evening gown at Bergdorf Goodman on Tuesday.
In reality, the 34-year-old star of Netflix's hit series Orange is the New Black will wear the custom-made Isabelle Armstrong gown when she hosts Bella New York City magazine's All White Party in the Hamptons on July 26.
Prepon shot to stardom when she landed the role of Donna Pinciotti on That '70s Show in 1998.
When the show's run ended in 2006, she went on to star in the drama series October Road which was canceled after only two seasons.
From there she made brief appearances on television series such as Castle, House M.D., How I Met Your Mother, and Medium.
Prepon struck gold when she landed the role of Alex Vause on the Netflix original series Orange is the New Black in 2013.
Based on Piper Kerman's bestselling memoir Orange is the New Black: My Year in a Women's Prison, the series released its much-anticipated second series on June 6, 2014.
In May news broke - via Prepon's Instagram feed - that the series had been renewed for a third season.
Prepon recently revealed that she'll appear in every episode of season three.
Many of Prepon's fans were disappointed when she appeared in only a few episodes of the second season due to schedule conflicts.
Prepon, who appeared on the cover of the July issue of Women's Running said she's never been more comfortable with her body than she is now, partially in thanks to Orange is the New Black:
“All the women on the show are different shapes, sizes, colors and creed - everything! You really embrace who you are, your curves and everything ... So if anything on this show, it’s the most comfortable I’ve ever been because all of us just really embrace who we are. It’s wonderful.”
