'She's already got the oldest boys [Maddox, 17, and Pax, 14] in her corner,' a source tells In Touch.
'Now, she's trying to get the four youngest [Zahara, 13, Shiloh, 12, and twins Vivienne and Knox, 10] on her side.
'She wants all the kids to tell the judge they want to live with her.
'She's begging them!'
In Touch claims Angelina has been spoiling her six kids in the hopes they'll want to stay with her full time.
'If they ask to go shopping, they go shopping,' says the source. 'If they want to go hiking, they go hiking. She's trying her hardest to spoil them,' especially since the judge forced the actress in August to hand over the kids to Brad.
Adds the source: 'She'll resort to any dirty trick to make sure she gets custody.'
