Kourtney Kardashian uses her ABCDEFG Goodbye phrase to shut down hater who told her she needs to cut five-year-old son Reign’s hair

And Kourtney Kardashian included a sweet video of her youngest son Reign, five, as he looked downstairs and outside at their waiting Easter baskets from the Easter bunny.

Kourtney, who is mom to Reign, Mason, 10, and Penelope, seven, took to her Instagram page Monday to share snaps from their Easter.

Reign, who wore his long brunette locks pulled back, sweetly looked down at their Easter goodies.

In the video, she tells him that the Easter bunny dropped them off, but Penelope can be heard saying that ‘no, I saw them in the garage.’ 

Kourtney told her she ‘must have seen something else.’

The adorable tot has always had longer hair, something which Kourtney has previously defended against haters.

This case was no different.

ABCDEFG is from her own speech from a previous episode of Keeping Up With The Kardashians when she was talking to Scott Disick.

During the episode, Scott is trying to agree on something with her, but Kourtney isn’t having it.

She tells him: ‘ABCDEFG… I have to go’ to which he asks her what that means.

She says: ‘It’s just a phrase I like use…that means the conversation is over.’ 

In the episode, she clarified that the G is goodbye.
