Madonna & Keisha Buchanan Team Up?

Madonna may have more than just Justin Timberlake and Timbaland in her pocket working on her next album.

Although the trio was spotted arriving at a Notting Hill recording studio in London on Wednesday, Keisha Buchanan was also seen entering the studio!

Keisha, 22, is the lead singer and a co-founding member of English girl group Sugababes and the only member of the original line-up to remain with the group.

Madonna seems like she’s ramping up on the collaborators for her forthcoming album!

P.S. Keisha also might recording demo tracks for her own un-released debut solo album.
