justin bieber selena gomez dateIt's not enough for Justin Bieber and Selena Gomez to be the most glamorous couple in the tweensphere -- they're apparently looking to ratchet up the star power with celebrified movie-going hang-outs.

According to Hollywood Life, Biebs and Gomez "met up with Selena's renewed BFF Demi Lovato and Justin's friend Chris Brown for a midnight showing of 'Pirates of the Caribbean 4: On Stranger Tides' at ArcLight theaters in Sherman Oaks, Calif. We spoke to four eyewitnesses who all confirmed they saw the gaggle of celebrity friends."

One source says the singing quartet were "so amped up to be hanging out they kept jumping up and down."

They were so thrilled to hang, in fact, they left the movie early.
