Britney Spears' ex-boyfriend Adnan Ghalib claims her mother told him to trash Sam Lutfi's reputation.

The Afghanistan-born paparazzo - who briefly dated The X Factor judge during her public meltdown in 2008 - told a jury that the popstar's mother Lynne Spears instructed him to lie to the media to make it sound like her ex-manager Sam was evil and manipulating Britney at the time.

According to gossip website TMZ.com, Adnan took the stand today to give evidence in Sam's defamation and breach of contract lawsuit against the 30-year-old "Till The World Ends" singer and her parents Lynne and Jamie Spears. He claims that Lynne personally ordered him to trash Sam to his colleagues and media outlets all over Hollywood in order to turn the public against Sam but he did not say whether he followed Lynne's alleged instructions.

Meanwhile, Britney's father Jamie admitted in court today that he once "touched" Sam during a physical altercation but denied attacking him and threatening to kill him. Last week scorned celebrity manager Sam - who currently represents Courtney Love - told the court that Jamie punched him in the solar plexus and threatened to kill him.
Sam is suing Britney for breach of contract as he claims they verbally agreed he would represent her for four years.

Britney's lawyer Joel Boxer is arguing that Sam was never legally her manager and has no grounds to sue for 15 percent of her earnings during that period. Sam is also suing Lynne Spears for comments she made about him in her 2008 memoir Through The Storm.
