Celebrity Gossip's

HOTEL heiress Paris Hilton is busting to show off her plumped up, er, pillows — fuelling speculation that she’s had a boob job.

The 25-year-old had no room to spare in her low-cut baby doll dress on a nightie out in Hollywood.

Celebrity-watchers were left guessing whether she’d got her top-floor lift from a plastic surgeon — or was just wearing a powerful push-up bra.

An onlooker said: “Her breasts seemed massive. Everyone was staring.”

Paris has often been pictured topless and four years ago a home sex video of her appeared on the internet.

In January, another online clip showed her flashing her boobs.

She is not famous for having a — how can we say — well-staffed front desk.

The onlooker added: “She’s known for her quite small boobs. It’s a surprise to see her busting out of her top.”
