What's going on with Justin Bieber? As People reports, he's been acting very oddly while in Massachusetts for a concert this week. On Tuesday, he was seen walking barefoot in Boston Public Garden, feeding squirrels, lying in the grass, and taking selfies. That night at his show, "He was in a glass box onstage. He was literally in a glass case of emotion," one concertgoer says. "He didn't even try. At one point he just stopped singing altogether." The following day, he was spotted in Boston Public Garden again; this time, he climbed a large tree and sat in it "listening to headphones ... with his arms up in the air," People says.
"That's the real Justin," a source assures TMZ, noting that all this behavior should not actually be considered strange because Bieber just loves the outdoors. But consider that Bieber also told fans this week he would no longer take pictures with them ... and he got a face tattoo. (More Justin Bieber stories.)
