It looks like Paris Hilton and Doug Reinhardt may definitely be back together. The on-again, off-again couple were seen partying in Las Vegas over the weekend.

The couple partied at Wasted Space at the Hard Rock Hotel and Casino for the Maxim's Hometown Hotties event on Saturday night.

Paris Hilton has hung life-sized pictures of herself in her boyfriend's house. The socialite has flown to Vancouver, Canada, to film a guest appearance in TV show "Supernatural" and insisted on leaving behind a lasting reminder for Doug Reinhardt, who she recently reconciled with following a two-month split.

A source said: "Before jet-setting to Vancouver, Paris had her team pay a visit to Doug's house, bringing over life-size photos of herself to hang throughout the mansion."

Paris Hilton's on/off boyfriend Doug Reinhardt hired a Fijian island to win her back. The hotel heiress - who reunited with "The Hills" star two weeks ago following a two-month split - has just returned from a romantic trip with Doug to the "private and beautiful" Wadigi Island, which he rented in an attempt to rekindle their relationship.

Doug wrote on his Twitter page: "Fiji is truly one of the most amazing places in the world. Wadigi Island in Fiji is the perfect romantic getaway so private and beautiful."

You'll find well-known brands like Jimmy Choo and Louis Vuitton inside Paris Hilton's house. But across the way sits another pink, two-story house, except inside it features labels like Jimmy Chew and Chewy Vuitton. The faux designer names can all be found in Hilton's two-story, 300 square foot dog house.

The $325,000 space could buy a few homes for the Americans who are currently losing their homes and jobless. But the only tenants here have names like Tinkerbell, Harajuku, Marilyn Monroe, Prince Baby Bear, Dolce and Prada.

Britain's late Princess Diana was Paris Hilton's idol. The hotel heiress says she was inspired by the princess - who died in a car crash in August 1997 - but now knows she couldn't live the life Diana did as she was constantly hounded by paparazzi.

Paris, who is often followed by photographers, said: "I always looked up to Princess Diana and all these women, and now I could never be like that. I want to have a family. I want to be normal. I want to be happy."
