Victoria Beckham has unearthed a souvenir from her Spice Girls days and shared a related photo over Twitter.

Posh Spice tweeted Thursday a photo of her holding the Viva Forever Posh Fairy doll and singing through its mini-microphone while standing against a pink background. She was wearing a simple black dress and a bracelet in the same photo.

The photo tweet came with the caption, "Finally!! I found someone to duet with on my Xmas e-commerce shoot! X vb."

Victoria's mother reportedly kept the doll as a keepsake of the singer-turned-designer's popstar past.

The Viva Forever Posh Fairy was featured in the music video of Spice Girls' Viva Forever released in 1998. The single was released as a farewell to Geri Halliwell, who left the group due to personal issues.

After Spice Girls disbanded, Posh Spice briefly pursued solo recording before finally venturing into fashion. But last year, she and fellow Spice Girls reunited for a special performance at the closing ceremony of the 2012 London Olympics, and was considered the most tweeted event that year.

Since becoming an international designer, Victoria has mostly distanced herself from her Spice Girls past, but the photo tweet had her fans delighted over her 'reunion' with her Posh Spice alter-ego.

The doll was the second of Victoria's memorabilia to surface before the public. The first was the gold and diamond coronet she wore when she married David Beckham in 1999 will be sold at Bonham's Auction House in London.

The coronet designed by Slim Barrett will be sold with the guide price of £25,000 (roughly AU$45,000) but experts said a die-hard fan may place a higher bid over the headpiece.

Meanwhile, following the photo tweet with the Posh Fairy doll, Victoria posted another photo over Twitter. This time, it was a photo of herself with a yellow bag on her head, saying "it's that time of the year again!"
