Ouch! Kourtney Kardashian can't hide her outrage after baby Tatum mistakes her for Kris Jenner despite 23-year age difference

Kourtney Kardashian was left stunned when her nephew Tatum, sister Khloe Kardashian's baby son, confused her for her own mother, Kris Jenner.

The 45-year-old Kourtney was still on her Australian holiday with Travis Jenner and her children, when she decided to facetime her sister Khloe

After talking about Khloe's Valentine's Day decorations and Kourtney's matcha latte, Khloe puts young Tatum on as Kourtney says, ‘Hi! Remember me?’ 

Khloe instructs her young son to say, 'Hi Aunty Kourt!' but Tatum says, ‘Lovey,’ referring to Kris.

Khloe says, ‘That’s not Lovey, it’s Kourt,’ as Khloe insists, ‘Kourtney, that’s not an insult,’ but Kourtney says, ‘Do I look like I’m in my 60s?’

Kourtney adds in confession, ‘Obviously, she’s my mom and she’s beautiful and she’s 20-something years older than me, so it’s not like the ultimate compliment. It kind of is, I guess.’

Tatum says ‘Hi’ to Kourt and tries to say ‘Kourt,’ as his aunt explains, ‘This Aunty Kourt, not Lovey,’ but Tatum says, ‘Lovey,’ again, as Kourtney goes outside to show them her view.

She shows them the islands and the Sydney Opera House and her flowers, adding, ‘Travis surprised me last night, it would be so your style. He had a white Rolls-Royce pick us up, take us to dinner,’ as they show footage of them getting in the car.

‘It was our Valentine’s Day and we had the best time. And then there was more of the same flowers in the hotel but we only got to stay for a couple hours but like I couldn’t with the baby and all the kids,’ Kourtney tells Khloe.

Kourtney adds in confession, ‘He flew back from wherever he was in Australia back to Sydney. It’s like very rare now that we would have time alone or go out to dinner or anything.’

A producer asks Kourtney, ‘Are you a romantic?’ She answers, ‘I’m definitely a romantic,’ as Travis interrupts her confession to bring her, ‘latte drink from whatchamacallit,’ as they kiss.

She tells him, ‘We’re talking about Australia. She says, “Are you a romantic?” I know Travis is a romantic, but are you, and I said yes,’ as Travis adds, ‘I think I brought it out in her.’

Kourtney adds, as Travis kisses her hand, ‘I was thinking like I’m a romantic with him,’ as Travis adds, ‘Yeah, ‘cause I remember someone I was just friends with would be like, “I don’t even like hugging people. I had to go to a hugging class,” that’s what you told me.’

Kourtney laughs as Travis kisses her again and says he’s going to go see their son Rocky before kissing again.

Back in Australia, Kourtney shows Khloe her new pajamas, adding, ‘Travis had them in the hotel for us, matching,’ before disconnecting the video call.

Hilariously, the rest of the family found out their 'biological age' on the finale, with Kris learning her body is actually six years younger than her physical age.

Kim found out she was nearly 10 years younger - 34 - but Khloe was 11 years younger - 28 - which thrilled the reality star.
