What kind of question is that?
Of course I'd do. She looks amazing and has a great body = Money.
And she has an individual Style, makes her own music, dances incredibly and sings like a goddess.
WHO THE HELL WOULDN'T SIGN HER ?!
You're the owner of a music label, would you sign the following artist?:
Christina Aguilera
Give reasons for your choice - why would you / wouldn't you sign the artist?
Would you have signed her when she first started out? Would you have signed her before / after Bionic?
Yes. She is a global superstar, I would make a lot of profit, and yes, I would keep her even after Bionic, one underperformed album is nothing to worry about.
Her voice is one of a kind. You won't get to find a vocal talent as amazing as Christina. So it's foolish to just let that rarity go. I'll definitely sign her to my label which in the first place is after real talent above anything else.
