London, Aug 2 (ANI): Reports that Brad Pitt and Angelina Jolie's relationship is on the rocks are making rounds once again after rumours that she threw a glass of red wine over him after a furious bust-up.

An insider has revealed to Life and Style Weekly that things are so bad between the couple that they have already discussed a possible custody deal over their kids - Maddox, 6, Zahara, 2, and Shiloh, 14 months.

Pitt hasn't adopted Jolie's second son Pax Thien, 3, as yet.

The source revealed that Jolie flipped and dumped wine over Brad during a recent holiday in France when they got into a fight over politics.

It seems that Brad, 43, had accused her of being "immature".

"Angie was cursing at him and ended up throwing a glass of wine in his face. Brad was absolutely disgusted by her behaviour," the Mirror quoted the insider, as telling the mag.

"Brad's just had enough of doing what Angie wants to do and following her around the globe," the insider added.

Sources also reveal that in the event that they split, the couple have agreed that Jolie would get prime custody of 14-month-old daughter Shiloh and their three adopted children Maddox, Pax, and Zahara. (ANI)
