Peter Andre has officially begun divorce proceedings against Katie Price after reportedly ignoring her pleas for a reconciliation.

All over: Katie Price and Peter Andre

The singer today met his lawyers to sign papers to end the three and a half-year marriage. Andre, 36, is said to have refused to meet his glamour model wife, 31, to discuss terms and will ask his legal team to thrash out custody arrangements for their children.

Price was snapped horse riding near her Surrey mansion yesterday morning before going home to see Andrew Gould, the married dressage coach said to be the reason behind the split.

Andre wants joint custody of son Junior, three, and 23-month-old daughter Princess Tiaamii, as well as access to Harvey, seven tomorrow, Price's son with footballer Dwight Yorke.

A source said: "Pete wants to get on with things for the sake of his kids and plough through with the divorce - the quicker the better. He doesn't want things to turn nastier. He just wants resolution, again for the sake of the children."

Andre was reunited with Junior and Princess on Saturday after 12 days apart and spent the day with them on Brighton beach and feeding the ducks at a local park.

He said: "I'm having a rough time, but my babies are a glimmer of sunshine in my life."
