36-year-old Kelly sparked rumours she was set to wed her French beau last month, after she was pictured wearing a diamond ring on her wedding finger.
Since the telling photo was uploaded to Instagram by model Jeremy, Kelly has chosen to ignore the speculation. However, a friend of hers has now said rumours that the couple are getting married are true.
According to The Sun on Sunday, Kelly's pal revealed she is set to wed again, telling the paper: "Jeremy is absolutely lovely. We're so happy for her. Have you seen the engagement ring?"
It also reports Kelly was congratulated on her exciting news and replied: "I can't say [if I am engaged] but thank you."
She is yet to make any comment regarding the engagement on social media.
Kelly has been dating Jeremy for nearly a year now. The pair first went public with their relationship in April 2015, sharing loved-up photos from their trip to Paris together.
Since then, their relationship has appeared to go from strength to strength, and Kelly has gushed that Jeremy is her "soulmate."
She has previously been engaged to Titanic star Billy Zane and CBB's David McIntosh.
Kelly and David's whirlwind romance saw them set to wed after just three months of dating. Things, however, didn't work out for the pair and after an on/off relationship, they split for good in early 2015.
