Glamourpuss: Jennifer Lawrence's allowed the mystery of her relationship with Darren Aronofsky to deepen as she swapped the ring for another jewel while blazing the promotional trail with new movie Passengers on Thursday

Jennifer, who was joined by her co-star Chris Pratt, looked sensational as she stormed the red carpet in a chic mullet hemmed gown with long sleeves - yet her sartorial statement was not the main focus of her look. 

On her ring finger, the American Hustle star wore a sparkling ring - although the jewel was different to the sparkler that originally set tongues wagging. 

With her blonde tresses scraped back into a mussed updo, the esteemed actress ensured she showed off her naturally striking face. 

Her make-up was perfectly applied, with smudgy eyeliner framing her almond-shaped eyes while she dabbed her pout with a nude gloss.
