Angelina Jolie & Brad Pitt, they are often refered to as the sexiest couple in Hollywood, but family and friends are afraid that Brad and Angelina will no longer be 'Brangelina' for all that much longer.

Hollywood's do-gooder duo have reportedly not been keen on the constant fights and bouts that have been putting an increasing amount of strain on their relationship, reports Zee News.

The pillow-lipped Jolie is said to be buckling under the pressure of postnatal depression, the fact that her mother is battling a serious illness, and the relentless attention of being one half of Hollywood's golden couple reports news.com.au.

Angelina Jolie recently indicated that she desired to escape the media circus that surrounds her, and spend some 'quality' time travelling in Africa while teaching her children about being 'citizens of the world' - an idea Brad has not been real happy with.

Jolie announced she was taking the children on a private trip to Namibia, where Shiloh was born in May.

"My concern is that Angelina thinks Brad is completely on the same page and wants the same things, and I don't think he does. There's no doubt he is in love with her, but she carries a lot of baggage .... She is most definitely not normal and that's one of the appealing things about her, but I think it takes someone pretty special as a partner to be able to deal with that. I think she just wants to run away," a pal is quoted by the U.K.'s Daily Mail.
