Paul McCartney took lover Nancy Shevell on holiday with his daughter Beatrice without telling ex-wife Heather Mills - who was furious when she found out.
The Beatle legend took Nancy to Morocco for a week to get to know Bea, four. Heather, 40, even helped plan the trip - and faxed the five-star La Gazelle d'Or hotel eight pages of instructions on Bea's vegan diet.
But she was not told Paul, 65, was taking new love Nancy, 47, for the holiday in April - and was angry when she later found out. A source revealed: "Paul had a lovely time.
He was keen for Bea to meet Nancy and for them to get to know each other. Paul kept Heather happy over the food issues, although he was more than capable of sorting it himself. The nanny came too, so Bea was well looked after.
"But he did not spell out to Heather that Nancy would be there. He felt it was none of her business who he chooses to be with.

"Heather made it clear later that she was not happy that he had kept her in the dark."
Sir Paul took Bea and Nancy to the hotel near Taroudant after spending a romantic week with his lover in Antigua. Since the Morocco trip their romance has blossomed.
Last night Nancy, first spotted enjoying a kiss with Paul in November, was expected to be by his side for a free concert in Kiev.
The source added: "Nancy is increasingly part of Paul's life. She's been welcomed into the family. He's getting more relaxed about being seen out with her. We're getting close to them posing for an official photograph."
Macca agreed a £25m divorce payout to Mills in March after a four-year marriage.
