According to the sources, Halliwell thinks the Spice Girls could do what the 2011 United Kingdom contestant, Blue, couldn't and bring home the victory.
So far, not the band nor the UK broadcaster, BBC, have confirmed nor denied the rumours.
The Spice Girls were a British pop girl group formed in 1994. The group consisted of Victoria Beckham (née Adams), Melanie Brown, Emma Bunton, Melanie Chisholm and Geri Halliwell .
They were signed to Virgin Records and released their debut single, Wannabe in 1996, which hit number-one in more than 30 countries and helped establish the group as a global phenomenon.
Credited for being the pioneers that paved the way for the commercial breakthrough of teen pop in the late 1990s, their debut album, Spice, sold more than 23 million copies worldwide, becoming the best-selling album by a female group in music history.
