We're just gonna come out and say it: Ed Kowalczyk, singer for overwrought '90s indie rockers Live, and Andre Agassi, '90s tennis star who used to sport a headband and mullet, look a lot like each other because of their big shiny domes.

Sure, we could make a case for the eyebrows, ears, posture and even facial expressions that the two share. But we'd totally be lying if we said it was something other than their bald heads that made us note their similarities.

But it's not just physical appearances that bring these two stars together. Kowalczyk is 41; Agassi is 42. Kowalczyk led Live to three Top 10 albums (two of them No. 1s) between 1994 and 1999; Agassi racked up five Grand Slam titles between 1992 and 1999. And Live briefly broke up in 2009; Agassi retired in 2006. But let's face it: It's their heads, right?
