The former TOWIE star made it clear on ITV's Loose Women that she has no feelings - good or bad - towards Mark and Michelle and would appreciate it if everyone could move on.
Lauren spoke out after being asked if she felt a tiny bit good that she was voted number one in a recent poll of bikini bodies envied by British women, beating Michelle who came further down the list.
Her answer? NO!
Lauren replied: "Can I just please put that to bed. That ship sailed so long ago. I have no feelings whatsoever good or bad. I've moved on, he's moved on, he's happy, I'm happy. I understand why everyone brings it up all the time. because of TOWIE and we were together, I get that. But trust me, now there is no hate, no feelings, nothing bad.
"I'm so happy for him and I'm happy in my own life and that's all I have to say."
Lauren and Mark dated for more than a decade before splitting in 2012. Their relationship ups and downs were immortalised in The Only Way Is Essex before Mark quit in series three and Lauren followed in series six.
After their break-up, Mark began dating Coronation Street actress Michelle Keegan, and they married in 2015.
Lauren, meanwhile, split from boyfriend Jake McLean in May following a four-year on-off relationship.
