American actress/singer Jennifer Hudson has offered a 100,000-dollar reward for the safe return of her seven-year old nephew, who went missing after the brutal murder of her mother and brother on October 24.

Officials have issued an AMBER alert, and Hudson has also issued a plea for help in finding her nephew Julian King.

'Thank you for all your prayers and your calls. Please keep praying for our family and that we get Julian King back home safely,' the New York Post quoted Hudson, 27, as having written on her MySpace Web page.

'If anyone has any information about his whereabouts, please contact the authorities immediately. Here is a picture of Julian and what he was last seen wearing. Once again, thank you all for being there for us through this tough time. Sincerely, The Hudson Family,' the former Amercian Idol finalist wrote.

Hudson's representative Lisa Kasteler issued a statement announcing the reward on her behalf.

'Jennifer and her family appreciate the enormous amount of love, support and prayers they have received while she and her family try to cope with this tragedy and continue the search for Julian,' the statement said.

'We ask that all inquiries be directed to the Chicago Police Department, Area 1 Detective Division at 312/747-8380,' it added.
