John Mayer is one present short this Christmas; girlfriend Jennifer Aniston gave her sole wardrobe item from her racy GQ cover shoot to Late Show host David Letterman last night. Aniston appeared to promote upcoming film Marley and Me and brought out a wrapped box when talk turned to her recent GQ cover in which she appears nude, wearing a strategically placed Brooks Brothers tie. Dave was thrilled and immediately threw off his tie so he could wear Aniston’s. I guess John Mayer won’t be missing a little tie when he can have Jennifer under the tree all for himself.
