The toyboy warns he'll now expose the big secret behind Peter's divorce from Jordan

Angry Leandro Penna is threatening to spill the beans on the real reason Katie Price and Peter Andre’s marriage broke up – including the big secret Pete said he never wanted his children to hear.

In a shocking boast, Leo, 27, tells Now: I will tell many things about them, why they both split.

‘I will tell some reasons and I will tell about other people.’

He added: I have a lot of information.’

Leo’s words will be devastating to Pete, 39.

In an interview in October 2011 he told Piers Morgan that he’d never speak publicly about the reason he ended his marriage to Katie, 34, in May 2009 because he wants to protect their children Junior, seven, and Princess, five.

He said: I would never end a marriage over something small or little things building up.

‘Something big happened, which I won’t reveal as I don’t want my kids reading it.’

An insider tells us: ‘Pete will be very worried what Leandro is going to say.

‘He’s deliberately never spoken about the reasons for the break-up because of the children.’
