Things are looking up — way up! — for Demi Moore. The 48-year-old debuted a perky, pumped-looking pair of boobs while strolling around downtown Manhattan on Aug. 26 — and her Two and a Half Men star hubby, Ashton Kutcher, 33, must be loving his wife’s sexy new accessories!

In her tight top, Demi’s amplified assets were on full display — and Dr. Milind Ambe, a plastic surgeon who has not treated Demi, tells Star that the actress; fuller breasts appear to be the work of a scalpel, not just a killer push-up bra.

“Given the round contour in the upper in the upper part of ther breasts and increased projection, this is more likely the result of breast augmentation,” the Newport Beach, Calif., doctor tells Star exclusively, adding that unlike lots of other stars, Demi — who has reportedly spent more than $350,000 being nipped and tucked over the years — likely opted for a smaller implant combined with a breast lift to give her a natural but fuller chest.
