Paris Hilton has reportedly split from Doug Reinhardt.

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

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

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 family holiday to Aspen, but decided not to at the last minute.

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

"I'm pretty sure that's why he went to Aspen... to hide out and try to get over her."

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

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

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

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

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

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

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

She wrote: "What a fun night! My mom and Doug were so cute dancing together! I love how my parents love my love! We all had a blast! Great night! (sic)"
