(Featureflash Photo Agency/Shutterstock.com) Russell Crowe’s two sons look so grown up! The two strapping lads have already outgrown their mother, Australian actress/singer Danielle Spencer, and they’re their father’s spitting image. Though they’re still teenagers, it’s clear that both boys will be just as handsome as their father. Russell Crowe’s Boys Aren’t So Little Anymore! Danielle Spencer rarely shows off current pictures of her two boys, Charles and Tennyson Spencer Crowe, but the singer-songwriter indulged her followers with a recent picture from Mother’s Day. Spencer stood between her sons, aged 17 and 13, and it’s definitely strange to see them towering over their “mum.”
