Despite her joy in adding a fourth adorable tot to the melting pot she's cooking up with Brad Pitt, Angelina Jolie is so brokenhearted over the January passing of her mother, Marcheline Bertrand, that she's been left with an empty stomach and featherweight figure, says her older brother.

"Angie has become very thin because she's grieving," James Haven tells the London Daily Mail. "It's even difficult for her to eat. I keep saying to her, 'Don't forget to eat.'"

Us Weekly recently reported that the perpetually globe-crossing actress was carrying only 109 pounds on her 5-foot-8-inch frame, a weight loss her doppelganger brother says is understandable given the sad circumstances.

"But you know she doesn't pay much attention to food anyway and she's been going through a process of grief like me," he explains. "She has not wanted to eat, nor has she been able to."

In addition to the ostensibly nonexistent state of Jolie's appetite, Haven also dishes about their estranged father, Jon Voight, whom he says was "so tough on our mother" when they were growing up. What's more, he laments, the actor has yet to properly express his sympathies over Bertrand's death from cancer at the age of 56.

"My dad left a voicemail message that was very kind, wishing condolences to me and my sister. That was what he did," reveals Haven in a tone the paper describes as "heavy with sarcasm." "At some point I've got to be able to let my bitterness and anger towards him go and I'm working on that now."

Sighs the uncle of Maddox, Zahara, Shiloh and Pax, "I believe my mother's in a better place. What I have to deal with is that there's no such thing as him making amends now -- he's lost his chance and that just makes me and Angelina even more upset."

It's not the only thing that makes him upset: He also takes issue with the long-simmering suspicions that his brotherly bond with Angelina has a wee bit of a "Flowers in the Attic" bent.

The whispers, you'll recall, went into overdrive after the siblings' infamously squicky smooch just before Jolie climbed on stage at the 2000 Oscars to collect her award for "Girl, Interrupted" ("I'm in shock. And I'm so in love with my brother right now," Angie told the squirming audience. "He just held me and said he loved me").

"I did not give Angie a French kiss," huffs Haven of their lip-lock. "It was something simple and lovely."

Less lovely, he tells the paper, were the lack of luxuries they had as kids despite their famous dad, including a dearth of wheels during his formative high school years, a teen trauma the not-at-all hyperbole-prone Haven describes as "one of the saddest things in my life."

"Try to imagine. You go to Beverly Hills High, one of the wealthiest high schools in the nation. Even the cheapest car that anyone has is brand new," he resentfully recalls. "All my friends are well off. I have a movie-star father and no car. It was debilitating. I did not go to the prom because I felt uncomfortable that Dad would have to drive me. It's an embarrassing thing."

Not quite overflowing with sympathy over his plight? Maybe this will help: "The significant years of dating and getting to know yourself, I didn't experience any of that," he kvetches. "I didn't experience what I think is one of the most important times in a person's life, and neither did Angelina. It affected both of us."

For Jolie, their vehicle disadvantaged youth taught her a valuable life lesson, according to her brother: "Angie has been driven to be an independently wealthy woman now because we saw what it was like to be at the mercy of someone who controls the money and pulls the strings."
