The craziness continues for Britney Spears – she wants to get pregnant by her former lover Adnan Ghalib so she can escape her father’s strict control, The ENQUIRER has learned exclusively.

In a letter intercepted by her father Jamie Spears, the pop tart wrote to Ghalib: "My dad can’t keep us apart if I have a baby with you," according to a source.

"When Britney’s dad read the letter, he was dumbfounded. Britney wrote it days after Jamie got a restraining order banning Adnan and her former manager Sam Lutfi from being near Britney or contacting her," the insider divulged.

A judge recently further tightened the reigns on Adnan by ordering him to stay away from Britney for three years, but that’s not stopping Britney from trying to sneak some love time with Adnan, the insider said.

"Britney is still trying to set up a secret rendezvous with Adnan sometime on her tour so she can get pregnant," the insider said.

While she continues to scheme over Adnan, the 27-year-old singer – who’s launched a comeback with her worldwide "Circus" tour – has repeatedly told her father that she is done with Ghalib and Lutfi, insiders say.

But she’s secretly contacted both men in recent months, begging them to help free her from her father’s conservatorship, say sources.

The bizarre letter was the latest salvo in her war against her father – and security guards handed it over to Jamie after discovering it during a search of Britney’s personal effects, said the source. Such searches are done regularly in an effort to keep Britney’s life under control, say insiders.

"In the letter, Britney told Adnan that having a baby would end her father’s ban keeping them apart," said the insider. "She said her father would be forced to allow Adnan in her life since he’d be the father of her child."

The "Toxic" singer directed Ghalib to meet her at different tour stops so they could try to conceive a child, even though her ex-husband Kevin Federline and their two sons are traveling with her, said the source.
