The X Factor star, 31, was pictured grinning from ear-to-ear as she arrived at the exclusive event, held in central London, and she definitely had a newlywed glow about her!
Cheryl almost seemed to be channeling bridal-style for the launch, as she opted to show off her slender figure in a floor-length nude gown with dramatic split and sweeping train.
Standing with one hand on her hip, the former Girls Aloud singer smiled for the cameras outside Avenue private members' club while a smartly-dressed Jean-Bernard (JB for short) proudly looked on from afar.
Cheryl's new perfume is called Storm Flower and it is a first for the Geordie star. Hosting the event was JLS's Marvin Humes - who is good friends with Cheryl - and he was also pictured arriving at the bash.
Once inside, the pair took to the stage in front of an excited crowd and Marvin interviewed Cheryl about her latest product.
Yesterday (23 July), Cheryl released a sneak peek advert for Storm Flower, which shows her ballet dancing to dramatic music.
Last night, she hinted that her launch had gone well by cryptically tweeting: "It's so amazing how a simple smile or one kind word from a stranger can affect your whole mood or mindset #beautifulpeople."
Meanwhile, earlier this week Cheryl and Jean-Bernard threw an extravagant wedding party for 50 close family and friends to celebrate their recent nuptials.
Last week, Cheryl stunned fans by announcing that she and 33-year-old Frenchman Jean-Bernard had married in secret on the private island of Mustique on 7 July.
