The mother of two took to Instagram today to share an adorable photo of her little boy Ace, and we can't believe how big he's getting. In the snap, the 2-year-old shows off his beautiful blonde locks as he's held by his famous mom as sips on a drink. The little guy wears a military-esque baby blue vest reminiscent of those worn by The Beatles on the cover of their album Sgt. Pepper's Lonely Hearts Club Band, and he looks extra stylish. Simpson herself even wondered if he might be a rockstar in the making. "Sgt Pepper or Jimi Hendrix? #ACEKNUTE," the bombshell captioned the cute family photo. Check it out below.
