Michelle, 26, is engaged to marry Mark Wright, 27, and has chosen Mark's older sister Jess to be an important role on the big day.
Jessica shared the happy news on her official Twitter and Instagram pages yesterday (26 April).
The TOWIE star posted a picture of the cute invite, with the simple message: "Id be honoured @michkeegan xxxx @wrighty_"
The beautiful invite, from Button Box Cards, reads: "Just a little note to say, Jessica will you be my bridesmaid on my wedding day?"
The upcoming wedding is set to be a huge celebrity affair, attended by Mark's TOWIE and I'm A Celebrity friends and Michelle's former Coronation Street co-stars.
The loved-up pair started dating in December 2012 and got engaged in Dubai in September 2013. Although no date has been set, Mark has previously talked about waiting until 2015.
This could be bigger than the Royal wedding - watch this space!
