Sons out, buns out! This Father's Day weekend we're celebrating the sexiest nude and shirtless son of famous Hollywood celebrities. When comes to these families, it's not all about genes, it's all about what's in the jeans. Psst: Big penises and butts. In the top ten gallery below you'll find some well-known celebrity offspring like Alexander Skarsgard, Scott Eastwood, and Michael B. Jordan as well as some lesser-known cuties like Guillaume Depardieu and Wyatt Russell. It's true what they say. Attraction is all relative.
