Sibling rivalry starts early in Rachel Zoe's family!
The expecting fashion designer told E! News' Alicia Quarles that her adorable son Skyler, 2, isn't exactly cool with the fact that he is going to be a big brother soon.
"He understands a little and I don't think he is that happy about it," she jokes. "He does not want to share his mommy. He doesn't even want to share his mommy with his daddy, you know? He's a little possessive."
Perhaps her little guy will be more comfortable sharing mommy once he starts school in a week.
