Britney Spears ex-husband Kevin Federline is reportedly taking legal steps to stop his ex dating British photographer, Adnan Ghalib

K-Fed is said to be concerned at the apparent hold that Ghalib has over his former wife, after the pair holed up together for two days following Brit’s release from hospital.

Insiders say that the wannabe rapper has started investigating Ghalib's immigration status in a bid to end the relationship

A source tells The Sun: "Kevin and his legal team want to get Britney away from him. They are concerned she has completely lost all sense of reality.

"Dating a photographer who has tailed her for months is like sleeping with the enemy. Kevin's team want him sent home if he hasn't got his papers in order."

Brit reportedly described Ghalib as her "only friend" after she was admitted to L.A.’s Cedars-Sinai medical centre following a stand-off with police at her Beverly Hills home last week.
