The Atomic Kitten star and 5ive singer Ritchie announced today that they'd ended their relationship but insisted it was amicable.
Now, Natasha has angrily slammed Twitter users who have been sending her negative messages or poking fun at the separation.
She retweeted one user who sent a now-deleted message, saying: "D**kheads like this make me sick!" Natasha then said: "It make me so angry that when your having a really tough time in life, all the scum crawl out the woodwork to troll you. Shame on u! (sic)"
The couple announced their split in a statement today, saying: "After careful consideration, we have decided to amicably end our relationship. There is no one reason for the failure of our relationship. Unfortunately it's just the way things have turned out and it's no one's fault. In the interests of our family we remain good friends and we hope that people will respect our privacy at this time."
Old friends Natasha and Ritchie had been together since 2013, when they rekindled their friendship while appearing together on The Big Reunion. Friendship led to romance. Their daughter Ella arrived in September 2014, and an engagement in October 2015.
Ritchie had been very supportive of Natasha while she was in the Celebrity Big Brother house last year, and she had gushed to her housemates and the Diary Room about how much missed him.
