You mean Debbie McGee?
Face shape, yes, but no other resemblance. DM's hair is bleached far more than Ali's colour - which could be natural anyway.
I think that Ali looks like Evita Peron - but only when the dreadful SCD make-up department have had their mitts on her.

When she's natural, she's gorgeous.
And ITT had the gall to do a feature on the said cosmeticists - sheesh! Did you see someone applying an extra two days of beard growth to Ricky using shadow?
