Looking good: Bea shows off the result of her exercise regime in on-trend orange dress and wedge heels
She was the frumpy teenager whose fashion disasters and fuller figure were only too reminiscent of her mother's often-criticised forays into the limelight.
But Princess Beatrice is rapidly metamorphosing into a stunning young Royal ready to snatch even Pippa Middleton's style queen crown.
Showing off her sleek figure in an on-trend orange dress, Fergie and Prince Andrew's 22-year-old daughter looked the epitome of relaxed glamour at the Monaco grand prix.
Her laid back look was accessorised with a narrow belt and neutral coloured wedges which gave her enviably toned legs a little extra length.
Beatrice strolled contentedly around Monte Carlo hand-in-hand with boyfriend Dave Clark, posing for photographs with other race-goers.

She stopped off to chat to Tamara and Petra Ecclestone, the daughters of Formula One mogul Bernie, and then made a suitably superstar departure in a private launch.
Her reinvention seems to have started when she started training for last year's marathon, shedding two stone. She credits a fitness regime based on exercise, lots of water and plenty of fruit and vegetables with keeping the weight off.

It’s a far cry from the less-than-flattering photographs taken of the princess in a bikini on the beach in St Barts in 2008.
Speaking about the pictures, she said at the time: 'I could probably do with losing the odd pound though, so perhaps it's the kick I need.
'It was such an unflattering bikini and I've got one that's so much nicer, so I could have kicked myself for wearing it.

'I thought people were a bit mean, although I know it comes with the territory.
'The trouble is, I don't have much confidence so it can be quite upsetting.'
The Princess's presence added an little extra spice to a particularly glamorous race.
New X Factor judge Nicole Scherzinger was in Monaco to support her boyfriend Lewis Hamilton, while rival Jenson Button's girlfriend Jessica Michibata was also trackside.
