Hotel heiress Paris Hilton's on-off boyfriend Doug Reinhardt is said to be treating her to a luxury holiday and expensive jewellery in a bid to secure their reconciliation.

Rumours are rife that the high-profile couple, who split at the beginning of the summer this year, are courting again after The Hills star Reinhardt made a number of posts on Twitter.com about his love life.

According to Britain’s Daily Mail, Reinhardt has treated Hilton to a five-star holiday on the private Wadigi Island in Fiji, costing 96,000 dollars, and a black pearl necklace priced at 80,000 dollars.

"I am having the time of my life. Doug has taken me on the most romantic vacation. He is my best friend," Contactmusic quoted Hilton as saying.
