Olivia Wilde will return to co-host the New York portion of Revlon's fundraising walk to support women's cancer research.
The actress, who is a brand ambassador for the beauty company, will team up with Emma Stone for the second time this year to host the 20th Anniversary of the fundraiser.
Actress Halle Berry will join the Los Angeles portion of the event, which raises funds to support women's cancer research.
"I am truly honoured to host the 2013 EIF Revlon Run/Walk for Women," Olivia gushed in an official statement. "Before joining the Revlon family, I actually participated in the Los Angeles event and still remember it as one of the most moving experiences I've ever had. At that time, I never imagined that I would become a Run/Walk host, let alone a two-time host! I urge everyone to come out and join me in New York on May 4. If you can't be there, you can still get involved by making a donation online to fight women's cancer."
Earlier this week Olivia attended a party hosted by Marie Claire in New York City to celebrate her April cover of the magazine.
The 29-year-old opted for a lovely yellow Monique Lhuillier dress from the Resort 2013 collection for the event.
The knee-length feminine frock contained a fitted top half that gave way into a full flared skirt.
Olivia paired the piece with a chic pair of bronze Jimmy Choo Lace sandals.
The star added a chic updo which was offset by a bright make-up look consisting of blue eyes, nude lips and red nails.
Her spring styling was fitting for the celebration, and the colourful look was a surprising departure from Olivia's usual dark-toned ensembles.
