They've vehemently denied that they plan to get hitched anytime soon.

But when Cheryl Tweedy stepped out in Paris on Saturday, she made no attempts to hid the wedding-style band that was on her ring finger on her left hand. The 34-year-old pop-star - mother of baby Bear and partner of One Direction star Liam Payne - is gearing up to take part in a swish L’Oréal event in the French capital. The ring appeared to be a €3,380 piece by the LA-based Jennifer Meyer. Indeed, the 18-karat gold Open Heart band is one of the designer's personal favorites. Handmade at her studio, it's punctuated with 0.50-carats of light-catching diamonds.

Otherwise, the former X Factor judge completed her outfit with a Cushnie et Ochs cutout ribbed stretch-knit bodysuit, priced at €333, and an Isabel Marant asymmetric silk maxi skirt, priced at €780. She also had on her favourite plaid over-the-knee boots from Off-White, which cost a cool €1,485.

Liam, 24, has said that he and his girlfriend of 18months are in no rush to get married - despite his habit of calling her his 'wife' during interviews. He furthermore told The Sun in early September that he'd like to have a sibling for Bear before tying the knot.

On Sunday, Cheryl will take to a specially-constructed runway on the Champs-Élysées. Designers showcasing their work include Emanuel Ungaro, Balmain, Mulberry and Elley, while Ms Tweedy will be joined by the likes of Helen Mirren, Jane Fonda and Irina Shayk.
