First of all, her show at Palats Ukraina was to become the most expensive concert in Ukraine’s history. Despite impressively steep prices, most tickets were sold, but lots of Kyivans still weren’t able to attend the show. Luckily, Christina agreed to give another one, a cheaper concert at Palats Sportu.

Skeptics don’t believe Aguilera will perform in Kyiv at all, after she abolished her concert in Moscow scheduled for Oct. 16. Yet optimists believe the 27-year-old singer will come and present her greatest hits album, “Keeps Gettin’ Better – A Decade of Hits,” to be released Nov. 11. With this album, Aguilera will commemorate her 10 years in the music industry. It will include the hits “Genie In A Bottle,” “What A Girl Wants,” and “Come on Over” from her debut album “Christina Aguilera” (1999),  two songs from her second full-length English album “Stripped”, including “Dirrty” and “Beautiful.” And, of course, the album couldn’t be complete without “Ain’t No Other Man,” a lead single from the last “Back to Basics” album, which won Aguilera yet another Grammy.
