Before dousing herself with a bucket of ice cold water in the name of charity, Gwyneth Paltrow challenged three people to take on the frigid dare Wednesday.
Standing in a dark bikini with her hair hanging down, Paltrow, 41, challenged Cameron Diaz, Stella McCartney and her soon-to-be ex-husband Chris Martin.
While Paltrow has kept a relatively low profile in recent weeks, Martin, 37 has been romantically linked to Oscar-winning actress Jennifer Lawrence.
The two reportedly shared a romantic date at Wolffer Estate Vineyard in Sagaponack, New York just before her 24th birthday.
Martin has yet to accept the challenge.
As of Thursday, the viral campaign has helped the ALS Association raise $41.8 million.
