She's one glam granny! Kourtney Kardashian reveals Penelope Disick calls Caitlyn Jenner her 'Grandma'

She was just a baby when her grandfather Bruce Jenner announced his plans to transition to female.

So it should perhaps be no surprise that Penelope Disick thinks of Caitlyn Jenner as her grandmother.

In a preview of Sunday's episode of Keeping Up With The Kardashians, the three-year-old's mother Kourtney reveals her daughter refers to Caitlyn as 'Grandma'.

'We were reading a bible book, and the angel in the book was this person with long hair and a white long dress,' the mother-of-three told her sister.

'Penelope was like, "That looks like my grandma."

'I was like, "Which Grandma? Bonnie?" She was like, "No." I was like, "Lovie? GG?" And she was like, "No," the 37-year-old recalled. 

'She goes, "My grandma that came with us to see Zootopia." Caitlyn.'

'So I was like thinking, "I didn’t even think Caitlyn was a grandma,"' she added of her stepfather. 'You know?'

Meanwhile the girls mother Kris Jenner has revealed her plans to change her name back to Kardashian.

The 60-year-old reality TV star changed her name after she divorced Robert Kardashian in 1991 and married Bruce.

In a deleted scene from  Sunday's Keeping Up With the Kardashians, Kris told her daughter Khloe that she still uses the famous surname to get reservations at restaurants.

She said: 'I call the manager usually and I say, "Hey! It's Kris Kardashian". I'm going to change my name back to Kardashian.'

When Khloe, 31, replied: 'Why? You haven't been that in over 24 years,' Kris insisted she was the 'original Kardashian', before Khloe, Kourtney and Kim, came along.

She said: 'I was that before you were that. I was the original Kardashian.'

Throwback: While it has been two decades since she was a Kardashian, the star argued she 'was the original Kardashian' when questioned by daughter Khloe

However, Khloe was unimpressed and claimed it was an insult to Kris and Caitlyn's two daughters, Kendall, 20 and 18-year-old Kylie Jenner.

She said: 'I don't care if you were that, that's bizarre. Why don't you go back to your maiden name? Keep Kris Jenner. Don't you think that's insulting to your two daughters?'

But a defiant Kris stubbornly replied: 'It just doesn't sound right. If Bruce can change his name to Caitlyn, I think I'm good.'
