Mark and Michelle, both 28, married last month in the showbiz wedding of the year and 30-year-old Jess revealed there wasn’t a dry eye in the house.
Speaking to the Daily Star, Jess said: “I cried at Mark and Michelle’s wedding, everyone did.
“It was so emotional to watch them have that fairytale. They’re so much in love and so happy.”
Jess – who split from long-term love Ricky Rayment, 25, in December last year – claimed she’s using her brother and new sister-in-law as inspiration.
She continued: “Obviously I looked at them and thought, like a lot of people, ‘that looks amazing, I hope I find that’.
“Mark was always romantic but he portrayed a different image because he had never met the one. Michelle was the right one. He knew from day one that he would marry her.”
Jess’ comments may come as a blow to Mark’s ex-fiancée Lauren Goodger, 28, who was in an on/off relationship with the former TOWIE star for 10 years.
Lauren and Mark were recently caught up in a public spat, when he attacked her on Twitter and accused her of being an ‘obsessed, embarrassing weirdo’ when she used her magazine column to dismiss rumours she still wasn’t over him.
