Kourtney Kardashian is pooshing away any speculation of sibling rivalry.

Though she and Kim Kardashian previously butted heads on season four of The Kardashians, the Lemme founder has no bad blood with her younger sister. In fact, when someone accused Kim of purposefully using an unflattering photo of Kourtney in a social media post celebrating her 45th birthday, Kourtney immediately shot down the claim that she "was not going to like" the tribute.
