Paris Hilton is off the market again.The socialite is back together with minor league baseball player and "The Hills" cast member Doug Reinhardt, a source tells Usmagazine.com, saying the two are "definitely happy again."Hilton and Reinhardt had split in June after dating for four months, but apparently things are hot and heavy once more - at least judging from Reinhardt's Twitter. "What an amazing weekend with my beautiful girlfriend. I love her so much!" he posted on Monday. The previous day, he wrote: "Laying in bed watching SportsCenter with my girl."Reinhardt, whom Hilton once called her "future husband," is putting his baseball career on hold while recovering from an injury, according to his Web site. He has previously been linked to "The Hills" star Lauren Conrad and Amanda Bynes.
