"Cheryl just wants to share her happiness with those closest to her and it will be throwing a party at some point later this week," a source told the Mail Online.
"She won't be renewing her vows or having another ceremony as has been reported, or even wearing a wedding dress.
"She's been so busy that she hasn't had time to see everyone since she flew back home, so this is the perfect opportunity for her and Jean-Bernard to catch up with their nearest and dearest."
