Selena Gomez Rocks Super Short Shorts At 'The Thing' Premiere

Justin Bieber is one lucky fellow. His lady, Selena Gomez, stepped out on the red carpet premiere of "The Thing" looking flawless in a pair of super short black shorts and a white, flowing top.

And it's no wonder that Gomez was glowing. Her boyfriend, Bieber, recently told New! Magazine, "I wouldn’t be with somebody if I wasn’t in love."

So what does this mean for the lovebirds? Bieber also explained that he'd like to have kids by the time he's 25 years old -- we wonder if Selena's on board.
