Dan didn't walk the red carpet at the glitzy Dorchester Hotel ceremony on Monday evening (9 September), but he was spotted looking very dapper in a black suit as he walked alongside Jacqueline after the event.
The reality star looked pretty happy to be with 20-year-old Jacqueline – and we don't blame him as she was looking stunning in her midnight blue gown.
The beautiful pair – who were also snapped waiting outside the hotel - were later seen driving away in a car together.
Dan and Jacqueline - who plays Lauren Branning in EastEnders - sparked dating rumours earlier this month when they were seen holding hands as they did some shopping in London. They've also been seen together at Rio Ferdinand's restaurant in Manchester.
Model Dan, 22, was recently linked to TOWIE co-star Lucy Mecklenburgh but ended their fling on the last series after discovering that his ex-girlfriend is pregnant with his first child.
Jacqueline, meanwhile, split from long-time boyfriend Tony Discipline earlier this year. She was later linked to co-star David Witts but swiftly denied any romance by posting a funny picture of the pair online in which they looked less than thrilled to be in each other's company.
(Pretending, of course!)
While EastEnders lost out on the 'Best Soap Award' to Coronation Street last night, there was success for Jacqueline's co-stars Shane Richie (Alfie Moon) and David Witts (Joey Branning), who won 'Best Soap Actor' and 'Best Soap Newcomer' respectively.
