With Paris Hilton potentially facing 90 days in the pokey for getting behind the wheel of her Bentley with a suspended license, it's likely she's looking for a little pick-me-up. But did she boost her spirits by beefing up her bustline?

The beleaguered starlet has been spotted out and about in recent days proudly displaying eye-popping -- and button-popping -- décolletage, which has prompted several outlets to speculate that she might have amplified her oft-flashed assets.

The London Sun labels the kerfuffle over Hilton's suddenly overflowing cups a "boob job riddle" (and somewhere, the Sphinx bangs its head against a wall) and quotes an ogling eyewitness as saying, "Her breasts seemed massive. Everyone was staring. She's known for her quite small boobs. It's a surprise to see her busting out of her top."

So did Paris, who has been sucking face in recent days with actor Josh Henderson, do a bit of nipping and tucking to soup up her rack, or is she a walking billboard for how a girl's breast best friend is a powerful push-up bra?

Hilton's ever-vigilant and raise-needing rep Elliot Mintz is quick to nip the mammary magnification talk in the bud.

When asked whether she's undergone an augmentation, he pooh-poohs to MSN.com, "She has not."

In 2004, Paris told Rolling Stone the idea of implants was "gross," explaining, "When I was younger, like, 16, I wanted them so bad. I was begging my dad, like, 'Can I get a boob job?' He was like, 'No.'"

Two years later, when she no longer needed daddy's permission to visit the plastic surgeon, she decided to nix the surgery after seeing what had become of her inflated pals.

"They look deformed," sniped Paris. "All my friends that have them, they look so gross. I'd rather not have any and not have to wear a bra."
