Former rugby player and Strictly Come Dancing contestant Ben Cohen is set to take his ex's mother to court later this month on a harassment charge.
The sports star was married to Abby Cohen, the mother of his twin daughters, for eleven years, before the couple split in 2014.
Ben now claims that Abby's mother Felicity Bassouls bombarded him with calls and emails after the split.
It's widely believed Ben and Abby's marriage breakdown was linked to rumours the rugby star had grown close to his Strictly partner, professional dancer Kristina Rihanoff, while appearing on the show as a celebrity contestant in 2013.
Both Ben and Kristina strongly denied there was anything going on between them, although the chemistry between them was widely commented on.
Last year it was revealed that Kristina had apparently been banned from partnering with married men on the show, after the break ups of Joe Calzaghe, Vincent Simone and then Ben were linked to her.
Back in September, Felicity branded Ben a "bully" and responded to his official statement about his split from Abby by saying, "I have experienced a great deal of bullying from you myself. Your behaviour has been so disrespectful and very intimidating not just to myself but my husband also."
She continued by saying, "I know you very well Mr. Ben Cohen and I am not going to stand back and let you bully and intimidate me again. You have broken my daughter's heart and the little girls' and also my heart."
Now Ben plans to take Felicity to court on a harassment charge, with a date set for later this month.
Sounds like a very messy split indeed.
