She's had to head back to work after a whirlwind couple of days celebrating her engagement.

But Pixie Lott turned work into a party on Wednesday night as she turned heads at the Hard Rock Cafe Paris' 25th anniversary bash.

The starlet dressed to impress in a stunning gold gown, but while she sparkled for the cameras there was still no sign of her new engagement ring.

The star showed off her trim figure in the tight-fitting gown which glittered under the red carpet lights.

The dress also featured a daringly low neckline, with Pixie's ample assets on display thanks to the plunging design.

Her blonde locks were styled into a sleek bob and swept back off her face to highlight her flawless makeup.

While Pixie wore a ring on one finger, there was no sign of her new piece of bling - a dazzling diamond ring from her model fiance Oliver Cheshire, who popped the question in London on Sunday.  

The couple headed to a London jewellers on Monday where Pixie vacated the shop without her eye-popping engagement ring.

The 25-year-old Cry Me Out hitmaker was grinning from ear-to-ear as she left the store in Hatton Garden, the home of the best jewellers in the capital.

Inside the shop she was seen poring over the rings - perhaps preparing to resize or exchange the eye-popping diamond which she left the shop without.

The couple have been enjoying a blissfully happy romance over the past six years and Oliver finally popped the question, proposing to his girlfriend in the heart of London.
