The Grammy-winning singer was allegedly in the studio with RnB maestros Soulpower, who have previously inked songs for Whitney Houston, Pink, Destiny's Child and Victoria Beckham.
The 25-year-old was said to have been recording with the Danish duo Soulshock and Karlin without her fellow 'Girls'.
"Soulpower are one of the hottest production pairings out there at the moment. They're hugely sought after and command a huge fee for their services," the Sun quoted a source as saying.
"They regularly write hits for American soul stars like Toni Braxton and Christina Milian. Cheryl really enjoyed her time in the studio with them," the source added.
Meanwhile, Cheryl has been voted the World's Sexiest Woman of 2009 in a poll headed by FHM. (ANI)
