Former TOWIE star Mark got engaged to Michelle in Dubai last week but cool as a cucumber he was certainly not.
Speaking to ITV's Daybreak at the TV Choice Awards last night (9 September), Jessica revealed: "He was really really nervous apparently. He was sweating and absolutely shaking in his boots!"
She then added: "I'm really really happy for them."
Mark's best pal and former TOWIE co-star James 'Arg' Argent was also at the glitzy event in London.
But when asked if he had given him any advice on his proposal tactics, Arg laughed: "No! I'd be the last person he'd ask for advice!"
Michelle, 25, didn't attend the TV Choice Awards, however she scooped the 'Best Soap Actress' gong for her part as Tina McIntyre in Coronation Street.
The star had only announced her engagement to Mark hours earlier, so literally couldn't believe her luck.
"WOW what an amazing day! I have to keep pinching myself. #solucky," Michelle tweeted.
