Janet Jackson's second wedding dress, from her 1991 marriage to dancer Rene Elizondo Jr., is up for auction next month.

The pop superstar's personal items are among the celebrity memorabilia in next month's Julien's Auctions sale.

The auction will honor Janet and her "groundbreaking four decade career that changed music forever and opened the door for an entire generation of music icons who followed her extraordinary path".

In addition to her wedding dress, the auction includes the futuristic outfits Janet wore in her "Scream" music video with late brother Michael Jackson. "Scream" was the world's most expensive music video at the time, at a cost of $7 million.

The items are up for sale on May 14, 15 and 16 - coinciding with the singer's 55th birthday on the 16th.

Janet was married to singer James DeBarge from 1984 to 1985. Her marriage to Elizondo lasted from 1991 to 2000. Her third marriage, to a Qatari businessman, ended in a legal separation.

The items will be exhibited at London's Hard Rock Cafe for five days from April 19, before being transferred to New York and then Los Angeles for the auction.
