The 41-year-old cage fighter was furious when his former spouse appeared to poke fun at his cross-dressing as female alter ego Roxanne when she spoke a recent encounter with Eddie Redmayne, who played Danish painter Einar Wegene, the first man to undergo a sex-change operation, in 'The Danish Girl'.
Katie said: ''I went to a party recently with all these A-listers and, I wasn't starstuck, but you're still in a room with this. They all knew who it was - and I was like, 'How do they know who I am? Little me.'
''I was talking to Eddie Redmayne about the scene he did in 'The Danish Girl'. I was telling him he played it well because it reminded me of someone I knew. I said, 'You actually played that part really well.'''
But Alex was annoyed by Katie's story and took to Instagram to slam her.
He wrote: ''@MissKatiePrice would think in 6yrs you'd of got bored talking about me.Theres a reason why you have no real friends
''Your a spiteful bully! #bully #cyberbully #harrassment #letitgo #gossipgirl (sic).''
Earlier this year, Alex criticised his ex-wife for having ''little'' understanding of transvestism and for having the audacity to suggest he could undergo a sex change in the future after she claimed she wouldn't be surprised if he ''does end up being a transgender''.
Alex rubbished he ex-partner's suggestion, insisting he identifies as male and always will and branded her comments as having the potential to incite ''hate and prejudice against the trans community''.
In a statement released to BANG Showbiz, Alex said: ''Katie Price's comments have a wide and very damaging reach, potentially inciting hate and prejudice against the trans community. Firstly, in expressing her ignorance towards what it is to be a cross-dresser, as opposed to being transgender opens to the door to further criticism for those going through what can be a very emotional time.
''Secondly, in suggesting I 'needed help' and that such help was offered and denied, further highlights how little she understands of the fundamental nature of someone who cross-dresses. The sniggering and coquettish giggling (on the show) actually upset me more for those facing ridicule every day, perhaps going through transition, as it somehow became a joke, something to be laughed at and made fun of, which is so far away from what the original topic was about. The panel were meant to be highlighting the fantastic work of Eddie Redmayne in 'The Danish Girl', a film based on the support of a woman for her transgender husband. What an insult to the movie and those who inspired it by allowing her to speculate on whether I was going to become a woman in future years ... For the record, I have no intention at any point of transitioning into a woman.''
Ahead of their upcoming tour, and prior to the release of their long awaited album, Smoke Fairies played a great warm-up gig at Elsewhere in Margate.
Gritty and involving, this small British thriller is like Memento crossed with The Bourne Identity...
