Amanda Holden arrives for her first day as host of Heart Radio Breakfast hours ...

She had a hectic weekend with the live Britain's Got Talent finale on Sunday night.

But there was no time for rest on Sunday night as hours after celebrating at the BGT wrap party, Amanda Holden, 48, was up bright and early for her first day as host of the new Heart Radio Breakfast Show.

The hard-working star was seen arriving at the Global studios in Leicester Square, a mere five hours after heading to bed at a hotel just feet from her new workplace, to ensure she was on time.

Hiding any sign of a hangover behind some large sunglasses, the blonde looked in great spirits as she walked into the studio, clutching a large box of donuts for her new workmates.

Taking to Instagram just a few hours earlier, Amanda told her fans she had a plan to make sure her first morning went smoothly.

Standing in the middle of Leicester Square, the star told the camera 'I've just come from the Britain's Got Talent wrap party, I am in Leicester Square. Here is Global.

She swung the camera around to show her hotel, telling her followers: 'I am staying at this hotel so that I will make it on time in the morning for Heart Breakfast at 6:30. I am so excited. I really hope if you're up that you tune in.'

Amanda is the new Breakfast Show host alongside Jamie Theakston, after reportedly landing £3million for a two-year contract, making her the best-paid female showbiz host.

The presenter revealed last month that the show will go national in the process, telling MailOnline that she is 'thrilled' and 'delighted' to be hosting to the nation alongside Jamie, four months after Emma Bunton stepped down from the show.

According to The Sun, Amanda will earn a whopping £3million over the duration of her two-year Heart breakfast show contract, meaning she will pocket more than Radio 2’s Zoe Ball, who earns around £1.2million a year. 

Amanda is currently estimated to be worth £6million, with that figure set to skyrocket thanks to a string of lucrative deals on top of her new radio gig. 

On Sunday night, Amanda led the way as the stars of Britain's Got Talent headed out to celebrate wrapping up the series after the finale at the Hammersmith Apollo.

The fashion forward star ensured she caught the eye - much like she has during this year's series with her wardrobe of risqué outfits - by slipping into a sexy little black dress.

The blonde bombshell was sure to set pulses racing in the satin mini-dress that featured one thin spaghetti strap and a drawstring up the side that allowed the silky material to be ruched up. 

Elongating her slim pins, the West End performer strutted along the pavement in a pair of black barely there heels.

Radiating beauty, Amanda sported a face of dewy make-up and amplified her pout with a slick of gloss. 

She pulled her hair down into loose curls - after modelling an exquisite up-do during the show.
