We all know the Kardashians love to go all out for a birthday celebration, and they've been busy spreading the love for one of the newer members of the family, Kris Jenner's boyfriend Corey Gamble.

Celebrating Corey's birthday on Wednesday [10 November], the Kardashian-Jenners were quick to rush in with birthday tributes for the 41-year-old - but it's Kim Kardashian's that stood out thanks to her fairly surprising choice of words.

Gushing about Corey on her Instagram Stories, Kim called mum Kris' boyfriend her 'step dad', despite the pair actually being the exact same age.
