Rose Byrne went to the New York telephone banks on Tuesday to raise money for vulnerable children.

The 39-year-old actress represented a charity for foster children during a fundraising event that was held every 9/11 by a financial institution in New York that lost 658 people 17 years ago in the terrorist attack.

There were tears like the star of Damages and X-Men: Apocalypse explained why she had become an ambassador for Happy Trails for Kids, raising money to help the 400,000 children of the nation in foster homes.

Rose said that Cantor Fitzgerald's Charity Day had become an important way to transform the horror of 9/11 into something meaningful and positive & # 39; for vulnerable children.

She joined a telephone bank on Tuesday afternoon at Cantor Fitzgerald headquarters in Seaport Plaza, where she has contact with customers to win pledges for the charity based in Los Angeles.

Rose worked the telephones alongside Edie Lutnick, 58, the sister of President Howard Lutnick of Cantor Fitzgerald.

They lost a younger brother, Gary, when on 11 September 2011 a plane was flown by terrorists to their old headquarters in the North Tower of the World Trade Center.

Since 2005, the annual charity day organized by Cantor Fitzgerald and its affiliated BGC Partners raised about $ 113 million for charities.

Celebrities who have participated in previous events include President George Bush, President Bill Clinton, Lady Gaga, Venus Williams, Eli Manning, Susan Sarandon and Prince Harry.

Byrne said she hoped her contribution was uplifting & # 39; would be, like her wardrobe – a stylish stripey suit with pink heels.

The Australian-born mother of two has been a regular patron of many charities, including UNICEF Australia.

But last year working on Instant Family, an upcoming comedy with Mark Wahlberg on the challenges of adoption, may have deepened her understanding of the problems of & # 39; lost & # 39; children who are looking for a home.

Since 1993, Happy Trials for Kids has helped generations of foster children discover the outdoors and guide them through educational and family matters.

Other stars who died at Seaport Plaza on Tuesday included Lucy Hale, the 29-year-old singer and star of Pretty Little Liars who looked businesslike in an MSGM suit and Nicholas Kirkwood heels.
