Brooklyn Beckham, the 15-year-old son of David and Victoria Beckham, appeared in his first modeling spot on the cover of Man About Town magazine, and the reaction he's getting from older women is making some a little uncomfortable. The oldest Beckham child appeared not only on the cover of the magazine, but also in several photos inside the magazine. Looking much older and more sophisticated than his 15 years, ladies young and old took to Twitter to gush over Brooklyn's appearance, commenting on his sex appeal. The phrase "Brooklyn Beckham can father my children" even trended in many of the comments. Now advocates against child sex are blasting some of the reaction Brooklyn's photo shoot has gotten. Phil Mitchell, coordinator of the BLAST Project, which advocates in support of male victims of sexual exploitation, asked whether people would have deemed it appropriate had the tables been turned and an older male remarked on a 15-year-old girl's sex appeal.
