We caught Justin Bieber during a boxing workout yesterday and when he spotted our chopper, the teen heartthrob did what any self-respecting pop idol would do ... he lifted up his shirt and showed us his washboard abs!

At least Bieber gives his Beliebers what they want ...

Now, onto another thing we spotted from the sky ... this pimped out Porsche, painted in custom leopard print. Uh ... we prefer the abs!
