After skinny dipping with model Sahara Ray last week, it seems as though Justin Bieber may already have moved onto his next summer fling. The singer was seen hanging out this week with Nicole Richie’s 17-year-old sister, Sofia Richie.

“The pair are casually seeing each other, but it’s nothing more than that right now,” a source tells US Weekly. However, it seems to be more than just hanging out. Before he left for his Purpose World Tour in Japan this weekend, Bieber and Richie were spotted holding hands while hiking near his Lake House in Tacuna Beach.

And if you’re still not convinced yet, Richie was also spotted leaving the pop star’s home on Tuesday morning wearing printed pajama pants.
