Gwyneth Paltrow's website has crashed after she used it for a "super classy yard sale" of old clothes including items once owned by Miranda Kerr.

The 41-year-old announced the sale on her lifestyle site GOOP, which she famously used to announce her "conscious uncoupling" from her now estranged husband Chris Martin in March.

Paltrow donated some of her old clothes as did many of her friends, with demand so high the site went offline for a while.

"Last year, we did a big story on closet organisation, and in the process, sold a handful of pieces on behalf of three charities," she said.

"It was such a success that we decided to do it again, and enlisted some friends-of-Goop, who have particularly outstanding personal style, to help this year."

Among those to offer up their worn items was Paltrow's close friend Kate Hudson, who donated a Balenciaga gown. Several dresses and tops which belonged to Kerr were also up for grabs, along with some of Nicole Richie's Christian Louboutin shoes.

Beyonce Knowles also got in on the action, donating footwear from her The Mrs Carter Show world tour.

The money raised will go to DonorsChoose, a charity which helps teaches get help for students in need.
