Julias Gown, Madness Returns, Caroling: London Weekend

Kylie Minogue joins with Jason Donovan to get Londons Christmas party started at the O2 tomorrow.

The Australian stars lead Hit Factory Live, a celebration of the music produced by Pete Waterman. Heartthrobs Steps, Bananarama, Rick Astley and Dead or Alive also feature. (The event had been due to take place in Hyde Park in July, then got canceled as heavy rain turned the site into a mud bath.)

Madness takes over the O2 on Saturday. Expect large doses of cheeky-chappie Cockney humor and hits such as Our House, Driving in My Car and It Must Be Love. The Camden nutty boys will also perform songs from their new studio album Oui Oui Si Si Ja Ja Da Da, released after their Jubilee and Olympics concerts.

O2, Peninsula Sq., SE10 0DX. Information: +44-20-8463-2000 or http://www.theo2.co.uk, http://blog.madness.co.uk/

Saturday

Remember the ivory-and-black gown that Julia Roberts wore to pick up her Oscar in 2001?

Its hanging on a mannequin in Valentino: Master of Couture, a handsome tribute to the Roman maestro held insid! e the grand riverside quarters of Somerset House.

Dont go expecting red gowns all over the place: A dizzying variety of cuts and colors are worn by mannequins parked on a high steel catwalk. Theres the dress that Jackie Kennedy wore to wed Aristotle Onassis, and the black crepe number that actress Monica Vitti pouted in for the 1961 La Notte (directed by Michelangelo Antonioni). It looks as if it was sewn yesterday.

Downstairs are vitrines crammed with adoring messages from Kennedy and Donatella Versace (You are and always will be numero uno, she gushes in handwritten Italian.) Theres also a 1991 apology note from Meryl Streep, who says shell miss Valentinos 30th-anniversary bash because we are expecting a baby that very weekend.

Who said fashion exhibitions were dull?
