KELLY Brook has signed up as the fourth judge on Britain’s Got Talent.

The beauty, 29, will join Simon Cowell, Piers Morgan and Amanda Holden later this year.

And Simon is planning to announce his newest signing later today after deciding he wanted to add someone to the panel last week.

Kelly only signed up for the reality show last night.

The third series of the Ant and Dec-fronted show will kick off in May, with Kelly starting to film auditions today in Manchester.

Her arrival on the show mirrors Cheryl Cole's on The X Factor last year.

Both girls are in their twenties and have sportsmen as other halves - with Kelly dating rugby ace Danny Cipriani and Cheryl, 25, married to Ashley Cole.

During The X Factor there were rumours of a feud between Cheryl and Dannii Minogue, with claims the 37-year-old Aussie judge was jealous of Simon's new "favourite".

And now Amanda, also 37, seems like she wants to give Kelly a run for her money on BGT.

The actress looked a million dollars as she left her hotel to go to the first auditions today, dressed in striking red stilettos and a short black skirt.

She has just returned from her honeymoon after tying the knot to Chris Hughes last month.

Last year BGT was won by 15-year-old dancer George Sampson.
