Christina Aquilera ‘Bionic’ album will be released on June 8. Amazon suggest a moderate level of interest in what was expected to be one of the summer’s biggest sellers. Howevere, Aquilera has canceled her summer tour just days after it went on sale, citing “prior commitments.” Emergency triage measures are being taken, of course. A new single,”Woo Hoo,” featuring Nicki Minaj, is being released to rhythmic top 40 radio today. Most significantly, Aguilera will perform on the American Idol finale Wednesday night, where it’s presumed she’ll sing the new, rush-released single and not the DOA “Not Myself Tonight.”
