Most awkward moment at Billboard Music Awards?

The 2012 Billboard Music Awards aired live on ABC Sunday night, and as with all awards shows, the actual awards were the last thing anyone was thinking about.

Drawing the most buzz: Miley Cyrus wore wore a short white Jean Paul Gaultier jacket … and nothing else (as in nothing that could be mistaken for pants). We get it, Miley, you’re all grown up.

Natasha Bedingfield sang “Last Dance” in honor of disco queen Donna Summer, who died last Thursday of lung cancer. But the performance was cut off by a commercial break, upsetting viewers.

Meanwhile, Pink lashed out at Chris Brown for lip syncing, tweeting, "One day if I lipsync, I hope I do it as well as him." And her husband appeared to take aim at Katy Perry's performance of "Wide Awake": "I'm pretty sure I saw my wife did [sic] that same performance, but she was 3 months pregnant and actually sang," he tweeted.
