It's her first day on the job, so you can't blame Alesha Dixon for wanting to make a good impression.

Arriving for the first live auditions of the new Britain's Got Talent series today, the ex-Strictly Come Dancing judge pulled out all the stops in a sexy yellow slit dress.

The former Mis-teeq singer, 33, joined her fellow judges Amanda Holden, David Walliams and Simon Cowell at the Lowry Theatre in Manchester.

While Dixon was going all out in her eye-catching dress and Christian Louboutin heels, heavily pregnant Holden kept it simple in a classic black dress.

The former Cutting It star, 40, is due to give birth to a baby sister for her six-year-old daughter Lexi in February.
