Miley Cyrus won’t be performing on American Idol‘s finale Wednesday, but it doesn’t look like the 19-year-old is too bummed out about it.

Earlier this week, the former Disney star was all smiles in L.A., running barefoot through a parking lot wearing skinny jeans and a revealing top. She showed off her slim figure in the low-cut shirt (which she wore without a bra!) and grabbed at the sides of her top to prevent a wardrobe malfunction.

Sources tell E! News exclusively that Miley had been invited to appear on Idol Wednesday for a “surprise appearance,” with producers wanting her to sing alongside finalist Hollie Cavanagh.

But it was too difficult to coordinate rehearsal schedules. “It’s not happening,” Miley’s rep tells E! News. “It didn’t come together in time.”
