We know the Jonas Brothers make the young girls squeal -- but thirtysomethin' guys?
TMZ spotted the Jonases making grand exit from their NYC hotel ... into the waiting arms of a pair of hyperventilating girls, who were nonetheless outnumbered by a smallish group of autograph seekers, all of whom appeared to be older than and equally male as the Bros. Not exactly what one would call their core constituency.
BTW -- that bodyguard -- yes, that's Big Rob, Britney's old pal and guardian.
Jonas Bros. Mobbed ... By Man-Fans?
