Biel's fiance Justin Timberlake beamed with pride as his partner accepted the honour, and the actress later declared on her Twitter.com page, "Was thrilled to be with these kick-a** women at variety powerofwomen event. So lovely, so unstoppable."

Heigl and Huffman were recognised for their devotion to cancer charities, and the former Desperate Housewives star, whose sister has faced breast cancer, told the audience at the Beverly Wilshire Four Seasons Hotel, "Allowing me to be part of a solution gives me hope."

Latifah was chosen as an honouree for serving as the founder of the Lancelot H. Owens Scholarship Foundation, which provides financial support to struggling students, and Berry was picked for her commitment to the anti-domestic violence organisation Jenesse Center.

Accepting her accolade, the Monster's Ball star pledged her devotion to the cause, telling the organisation's executive director, "I will never leave this place."
