The Britney breakdown saga continued this week, when Kevin Federline revealed that he thought his ex-wife would kill herself and their two sons in a shocking confession to his current girlfriend, Nicole Narain.

In a terrifying tell-all to The News of the World, Nicole revealed Kevin's fears for the troubled singer and painted a damaging picture of the 25-year-old fallen star, just one month after her bodyguard also accused the troubled singer of being way out of control.

Court room catastrophe
Having managed to get away with the two outstanding hit and run charges bought against her, you'd think that Britney's latest custody courtoom appointment would see a more grown-up and calm Britney. But you'd be wrong.

Facing her ex, Kevin in the LA courts for the first time (she hasn't attended any other appointments), the mum-of two ended up running out of court screaming, "Eat it, lick it, snort it, f*** it," after the judge decided to postpone making a decision on Britney's custody application.

K-Fed's fears
Currently fighting for custody of Jayden James, two, and one-year-old Sean Preston, doting dad Kevin is desperately worried that Britney's erratic lifestyle is putting their two young sons in severe danger.

"Britney's behaviour has already put our kids at risk and I can't let things get any worse," the rapper told his Playboy model girlfriend. "She's lost all grasp of reality and is dragging the children through hell. Her mood swings are now so wild that I live in fear of getting a call telling me that she has killed herself."

"Britney wants Kevin back"
After Britney's attempts to win Kevin back failed, the star has allegedly become suicidal over the knowledge that she and Kevin are over forever.

"Britney's bouncing off the walls," spilled one mole. "She's crying all the time. It's not the first time she's been suicidal."

And Nicole reveals that Kevin is determined not to let their mother's very public troubles affect the two children.

"[Kevin] gets so upset when the kids are with her that he won't switch on the TV, as he knows there will be news footage of her with them in LA," revealed Nicole. "He never shouts and screams about Britney in front of me, but Kevin is worried about the damage Britney's lifestyle is doing to their sons."

His final straw
Nicole also revealed the reason why Kevin and Britney finally split and Kevin demanded full custody - he was convinced she was poisoning their son with alcohol!

"I'd see her walking around the house guzzling vodka and coke and looking very tipsy [then she'd] start breast-feeding Jayden," Kevin explained to Nicole. "That sent me up the wall... I was terrified she was poisoning my son."

"The kids are in danger"
Kevin also revealed why he doesn't want Britney to be in charge of the boys, claiming she "could harm our sons".

"I know she's capable of anything with pills and a few drinks inside her," explains Kevin. "She'd leave the kids near the pool unsupervised or drive around without belting them in." And Nicole also added, "[Kevin] says [Britney] keeps them up and has no fixed routine, which makes them over-stressed, over-tired and desperate for attention."
