Paris Hilton's on/off romance with Doug Reinhardt is giving her Hollywood neighbours a headache - they were forced to call in the police following a noisy disturbance in the early hours of Wednesday.

The socialite reunited with Reinhardt earlier this year after a brief split, but their relationship has been dogged by reports of arguments and fights.

Cops were called to Hilton's Hollywood Hills home last month after receiving noise complaints from annoyed locals, and they paid Hilton another visit on Wednesday when concerned neighbours witnessed a heated altercation turn ugly.

According to TMZ.com, Reinhardt was climbing into his car to leave when Hilton pleaded with him, "Don't go, don't go!"

The reality TV star then got out of his vehicle and the couple began "shoving each other" before returning to the house.

Police officers arrived at Hilton's home shortly afterwards to speak to the star and left without incident.
