Mark and Lauren, both 28, dated on and off for 10 years, but in May he married Michelle Keegan.
Writing in her column for Star magazine, TOWIE star Chloe said: “Lauren and Mark were in love for 10 years, engaged and on a national TV show together, then suddenly he’s with Michelle Keegan, one of the sexiest women in the world.”
Despite actress Michelle’s beauty, Chloe thinks that Mark could be kicking himself over how amazing Lauren looks lately.
She continued: “The tables have finally turned. Now all the trolls have changed their tune and they’re saying Mark’s made a mistake!”
Earlier this year Mark received Twitter backlash when he attacked Lauren on the social media site.
After she was asked about him in an interview, he fumed: “If you’re reading this, please PLEASE respect my wife and STOP. Everyone has a past, get over it! I really didn’t want to have to do this but enough is enough.”
Chloe, 32, also opened up about her own love life, after ex-boyfriend Elliott Wright went public with his new girlfriend last week.
Mum-of-one Chloe said: “I’m really happy for him. I would have kept my private life private until he moved on – and now he has, it means he won’t be upset if I do the same.”
