Paris Hilton has reportedly split from Doug Reinhardt again.

The socialite reportedly called time on their 14-month romance recently, despite speculation they are planning to marry.

Paris, 29, was seen partying in Las Vegas last weekend and Doug was reportedly planning to fly out to see her on his way back from a relatives holiday to Aspen, but decided not to at the eleventh hour.

A source said: "Obviously they broke up with him."

The source added to E! Online: "He was in Aspen with his dad this weekend and was thinking about stopping by Vegas on the drive back, but changed his mind.

"I'm sure that is why they went to Aspen... to hide out and try to get over her."

They tweeted: "Just packing my bags, going on a trip with my parents for a few days. I am liking spending time with my relatives, they have the best time... After dinner with the relatives, they all stopped by Tao. Had a great time dancing to DJ Reach. My parents are so much fun to hang out with."

Paris chose to spend time with her parents, Kathy and Richard, at the weekend and even went clubbing in Vegas with them.

Earlier this year, the couple spent a week with his brother Kelly and stepfather Duane Roberts at a luxury villa on the Caribbean island of Anguilla, where the former 'Hills' star's relatives were referring to Paris as "daughter-in-law".

News of a split is sure to disappoint the families of Paris and 24-year-old Doug.

A source said at the time: "Paris and Doug looked like they were on a honeymoon. They would be on the beach for hours, staring in to each other's eyes, kissing and laughing.

"At dinner Doug's mom was overheard referring to Paris as her, 'daughter-in-law' and it is clear that Paris' relatives feels the same way about Doug."

After a night out in February with Doug and her parents, Paris tweeted about how pleased they was at how well they got on.

She wrote: "What a fun night! My mom and Doug were so cute dancing together! I am liking how my parents love my love! They all had a blast! Great night!"
