Courtois and Dominguez who have been dating since his days in Spain, have ended their relationship.
Courtois and Dominguez have been dating since his days in Spain on loan at Atletico Madrid.
The goalkeeper and Dominguez have one child together and are expecting a son.
The Belgium international announced that he and the Spaniard parted ways in September 2016.
“My girlfriend Marta and I are no longer together. Since the beginning of September, we have decided to end our relationship, on amicable terms," the statement read.
“We both went our own way, even though she was already expecting our second child. She moved to Madrid, I stayed in London.
“We still love each other and we get along very well, but we don't have a romantic relationship anymore.
“But we don't run away for our responsibilities. We are first and foremost parents of a beautiful princess, Adriana, and our about to be born son, Nicolas.
“We'll strive to give our children the love and attention they deserve. Marta and I will be still present in each other's lives, as good friends and the best parents for our two kids.
“Their luck is our priority. In the meantime we're looking forward to the birth of our second child.”
Dominguez has since relocated to Spain where she plans to raise the kids of her and Courtois.
This split could be good news for Chelsea fans who are scared of losing Courtois to Real Madrid.
They have been reports that the goalkeeper was being forced to accept Real Madrid offers so he could move to Spain with his then girlfriend, Dominguez.
