Bryce Harper wasn't voted into the All-Star Game, nor was he immediately selected as a reserve, but he became a reserve after some players in front of him became unavailable. Bryce Harper is already an All-Star, technically and truthfully. He played and reached base. A thing happened, and there was a tweet about it.
Who knows how much truth there is to that? There's presumably not zero truth to it, because Fielder wouldn't have a reason to lie. Bryce Harper -- a not-even-in-the-majors-yet Bryce Harper -- was one of the reasons Fielder almost signed with the Washington Nationals as a free agent. Doesn't that seem crazy? That seems crazy!
