TOWIE star Jess has been watching Mark progress through the BBC One dancing show each week and admits she couldn't be more proud.
However, saying that, she would love the chance to take part in Strictly too – providing she makes it further in the programme than he does!
During an appearance on Radio 1Extra yesterday, Jessica said: "I definitely would consider going on the show, I love it.
"But if I did it, it would be a competition and I'd have to get further than Mark!"
Mark is going from strength to strength on Strictly Come Dancing - and some fans have even tipped him to win!
Speaking about her brother's success, Jessica continued: "I can't believe how well he is doing.
"He's never danced before and he had two left feet, but where it's a competition he can't fail. I'm so proud of him.
"I always get a bit teary watching him - I'm like a proud mother! I danced growing up and he played football – so it's like me playing football all day!"
Meanwhile, Jessica spoke about her own career on Radio 1Xtra, revealing that she is hoping to release new music next year.
The singer said: "I did three singles and we're just in talks again about doing something else.
"I'm just listening to tracks at the moment and co-writing to try and get something good."
