The 30-year-rapper - who is married to reality TV star Millie Mackintosh - admits he was blown away by the 33-year-old star's stunning looks when he locked eyes on her at Riccardo Tisci's 40th birthday party in Ibiza.
Speaking to radio station KISS FM UK, he said: ''Kim's gorgeous in real life, I mean in person I was astounded with her beauty.''
He explained: ''Kim's mum as well, she's wicked, we met her in the hotel before the party and then a few hours afterwards. She was having a good time.''
Meanwhile, Pro Green - whose real name is Stephen Manderson - announced plans last month to curb his excessive use of Twitter because he's sick of the banality of his online interactions.
He said previously: ''I'm having a reboot, a digital do-over. I've been on Twitter since January 2009, and I'm tired of the digital diarrhoea that has spewed forth from my fingers in the 140 format.''
