As if Jennifer Aniston, the tabloids' Most Brittle Cover Girl, didn't have enough psychic pain to deal with following the end of her suspicious partnership with The Break-Up co-star and noted co-ed cuddle-bear Vince Vaughn, Us Weekly reports that the actress has been dealt a severe blow to her always tenuous emotional health (hey, read the glossies! She's one long-distance phone service commercial from a stay in the Fragile Stars Wing of Cedars Sinai) by the latest round of pictures of Shiloh Jolie Pitt, the genetically perfect offspring that ex-husband Brad Pitt should have put in her uterus, not that orphan-collecting homewrecker's. "Close pals" tell Us that Aniston has been so affected by the widely circulated images of Shiloh that "she collapses in a heap, clutching her womb like she's been stabbed if she so much as passes a baby stroller on the street," and has taken to "throwing baby dolls into a bonfire on the beach behind her place in Malibu. It's creepy, but she says it makes her feel better for a few hours." The friend, however, offers hope that Jen's heart is on the mend: "At least she's stopped watching Mr. & Mrs. Smith over and over again, for days at a time without eating or sleeping. That just wasn't healthy."
