Malia Obama was spotted among the crowd of concertgoers at Lollapalooza over the weekend.

A flurry of tweets from folks attending the Chicago music festival on Sunday night mention eyeing the 16-year-old West Wing resident.

A Twitter user even posted a pic with the elder of Obama’s two daughters, who’s seen posing with her mouth agape.

The Chicago Sun-Times reports that Obama, who turned 16 last month, was “flanked by two huge guards.”

The annual music festival was created in 1991. This year’s lineup included Eminem, Kings of Leon, Lorde, Outkast, and Calvin Harris, among others.
