It's getting warmer and warmer day by day in L.A and one other thing that's heating up is Selena Gomez and Justin Bieber's on/off relationship. This weekend we spotted Selena returning home Saturday morning after spending Friday night at Justin's. "Selena looks like a young girl in love. And obviously Justin's trying to win her back - sending her home in his car and everything - giving her the royal treatment", a photographer from the scene tells. Justin and Selena broke up over New Year's in Mexico after a big fight, but we're guessing she's heard Justin's new song, Nothing Like Us, that is said to be about her - and fell right back to where she belongs, in his arms!
