Paris Hilton's boyfriend Doug Reinhardt is facing a lawsuit from his former landlord, over allegations he trashed the Los Angeles home which was rented for his stint in The Hills.

Last September, Reinhardt sued landlord Mark Rooke after the real estate developer refused to repay a $24,000 security deposit over to damage to the property caused by filming the hit MTV show. Reinhardt demanded the full amount back, minus the $2,332 he agreed to pay in repairs.

However, Rooke is holding on to the deposit - and is countersuing the baseball player, accusing the sports star of causing "substantial physical and other damage" to the house.

The landlord also targets MTV bosses in the suit, claiming they trespassed on the property, therefore breaking his initial contract with Reinhardt.

Rooke is seeking unspecified damages, as well as legal costs.
