Randy Jackson speaks with EW.com about Carly Smithson’s absence from last night’s American Idol:

Astute readers of EW.com’s American Idol TV Watch pointed out that only 11 of the 12 female semifinalists were in the audience during last night’s men’s semifinal performances. Missing from the group: Carly Smithson, the Irish-born songbird who’s been under intense media scrutiny because of her one-time deal with MCA Records.

But conspiracy theorists wondering if the controversy got Smithson booted from the show should hold their horses. Randy Jackson, who dropped by EW.com headquarters to shoot an episode of Idolatry this afternoon, attributes Smithson’s absence to a flu bug that had hit several female contestants this week. “I think they didn’t want them infecting the others,” Jackson said. “They were doing sort of an Idol quarantine.” Asked if viewers were in for a surprise on tonight’s women’s semifinal show, Jackson couldn’t have been more adamant: “No, no, no, definitely not.”
