Looking seriously HOT, the mum-of-one worked the red carpet, flashing her enviable pins with a thigh-high split.
Letting her super-stylish strapless black dress take centre stage, Alesha simply accessorised her outfit with a gold chain necklace and bangles to match.
To finish her look, the 36-year-old teamed her frock with a pair of T-bar sandals, wearing her long locks sleek and straight behind her shoulders and a slick of hot pink lipstick on her lips.
Totally gorgeous, right?!
Last Friday, it was confirmed Alesha would be reclaiming her judging seat on Britain's Got Talent along with her fellow judges Simon Cowell, David Walliams and Amanda Holden.
Despite rumours Simon was keen to shake up the panel this year, it seems the music mogul decided against bringing new names in.
And clearly pleased with his decision, comedian David couldn't wait to be back by Simon's side.
Sporting a kilt for today's auditions in Scotland, David joined his boss on the red carpet, and the pair were all smiles as they reunited. Cute.
The pair were then followed by Amanda Holden who made sure to stun in a beautiful off-the-shoulder red number. Like Alesha, she too opted to sleekly style her locks, finishing her look with a very glamorous Hollywood pout to match her dress.
Yesterday, the former This Morning presenter gave fans a glimpse at what life is like for a BGT judge, posting a photo of herself, Alesha and David being whisked off to Edinburgh on Simon's private jet.
Not a bad way to travel, ey!
Alongside her snap, she tweeted: "Waiting to board Simon Air! @BGT @AleshaOfficial @davidwalliams #BGT2015." And it looks like they were waiting for a certain Mr Cowell to arrive too!
This year's series of Britain's Got Talent is set to air later this year. Following today's auditions the panel will make their way across the country, wrapping things up in London before choosing which contestants will make the live shows.
As before, the winner will then perform at the Royal Variety Perfomance 2015.
Speaking ahead of the auditions in Edinburgh today, Simon has said: "I'm really looking forward to starting auditions on Britain's Got Talent. I feel very confident in my role as a judge on the show and I look forward to hopefully finding a star.
"Amanda is so much fun to work with and has great instincts. Alesha has proved to be a brilliant judge, has an amazing eye for talent and is a pleasure to be around. And, then there's David..."
Oh Simon, we know you love him really!
Last year, five-piece band Collabro were crowned winners of Britain's Got Talent.
