Kevin Federline owes over $110,000 in unpaid rent and damages after abandoning his home.
The dancer - who has two sons, Sean Preston, four, and Jayden James, three, with ex-wife Britney Spears - allegedly infuriated landlords of his rented Los Angeles home by disappearing without paying the last six months of rent and leaving the property uninhabitable.
Photographic evidence shows cigarette butts and glass bottles tossed across the garden and in the gutters, drawings over the walls, a broken dishwasher and damage to smoke detectors and light fittings.
The aspiring rapper also had tinted windows installed in the bathroom and converted another room into a studio without permission.
A source said: "The landlord was distraught when he saw the state of the house.
"Everything was broken and even the garden lampposts were bent."
The unnamed landlord has sent a letter to Kevin, 31, demanding $110,661 in back rent and compensation or he will take legal action.
A spokesperson for the star is unsure why the house has been left in such bad condition or why the rent wasn't paid.
The representative added: "His agent, manager and lawyer no longer work for him. NOne Of Us have any idea what is going on."
