You'd think that after nearly 16 years of marriage and four children, Victoria Beckham would have memorized every single millimeter of David Beckham's body by now. We know we have. And, we're pretty sure her nickname for him, Golden Balls, isn't merely a reference to his prowess on the soccer pitch. And yet, the fashion designer got majorly stumped when Ellen DeGeneres challenged her to play "Tats on Becks" on The Ellen DeGeneres Show today. The game involved identifying which Becks tattoo went where, and Posh Spice didn't exactly pass with flying colors. In her defense, he does have a lot of tattoos. Plus, it's not like David can, say, name the lyrics to every single Spice Girls song, or name-check every color featured in her Fall 2015 collection. Maybe some married couples just need to keep a bit of mystery — like, say, the exact body coordinates of a certain tat. Or, as Victoria put it, "I need to look at him more."
