Rob Kardashian has shockingly admitted his childhood crush was his own sister Kim.
In a bizarre exchange with fiancée Blac Chyna filmed for E! the pair were heard discussing their former favorite pin-ups.
While Blac’s was singer Ricky Martin, Rob stunned fans when he admitted his was curvaceous older sister Kim, 35.
Laughing Rob says: ‘Her childhood crush is Ricky Martin.’
Blac is then seen bursting into a rendition of Martin’s hit song Livin’ La Vida Loca.
But she fast got her own back when she outed his former crushes as Jennifer Lopez and sister Kim.
Rob blushes before responding: ‘That is also pretty accurate…’
‘These are facts’, Blac Chyna replied.
Unsurprisingly fans of the show took to social media shocked by Rob’s admission.
One said : ‘I’m sorry it’s been a long day. Did he just say he crushed on his SISTER?! Or did my exhaustion mishear things?’
The new clip comes amid rumors of a break-up for the expectant couple.
But this week the 29-year-old reality star seemed to have things back on track with Blac, as he shared a Snapchat video on Wednesday night of her pregnant belly.
In the video Rob was trying to capture their baby girl kicking, but noted she ‘aint moving for the camera’.
It was the first public display of unity between Rob and his 28-year-old pregnant fiancee since family drama earlier in the week that ended with Rob sharing sister Kylie Jenner’s phone number on Twitter.
