We didn't think Beyonce would start wearing mom jeans after having daughter Blue Ivy in 2012, but we weren't expecting this.The superstar singer was photographed boarding a yacht in Ibiza, daughter on her hip, wearing towering platform heels from Azzedine Alaia, according to The Daily Mail.This is after she just flew in from a performance in the US.Not only do the admittedly gorgeous shoes not look sea-worthy, we're a little worried they might not be safe for the slippery, bobbing surfaces of a boat, especially when you’re holding a small child. (At least Victoria Beckham was on terra firma in her crazy-high heels.)Hey Bey, take a style note from Blue, who looks totally adorable -- and comfy -- in her purple printed romper and bare feet.
