Britney Spears is reportedly desperate to get back with ex-hubby Kevin Federline since it is the only way the latter will drop the custody battle for their two kids.
Reports claim that after K-Fed, who is said to be dating playboy babe Nicole Narain, snubbed her offer, the singer called a suicide help line.
"Britney's bouncing off the walls with rage and has been calling Kev day and night to check he's not with Nicole," News of the World quoted a source as saying.
A distraught Spears, who has been ordered to take psychological tests, is also contemplating fleeing to Cuba with her two sons, a source revealed.
"She's crying all the time. It's not the first time she's been suicidal," the source said.
"She's terrified of losing her sons. There are no extradition laws in Cuba, so she thinks it's her only hope," the source added.
