Internet gossip sites are all abuzz about Lindsay Lohan’s premature aging.

Recent pictures show the Irish-American actress looking a bit worse for the wear, and many say her hard-partying, over-tanning ways are to blame.

A leading celebrity surgeon backs up this fact, saying the 23-year-old has the skin of a woman in her mid-30s.

Alex Karidis told Britain’s Closer magazine: “She looks at least 10 years older. Those deep creases on her forehead are probably caused by a combination of things, including sun damage, smoking, and too much boozing, which dehydrates and ages the skin."

And believe it or not, the tabloid queen’s Irish roots (and thus pale skin) may attribute to her haggard appearance.

"When you're young, you think you're invincible. But with pale skin like Lindsay's, it just shows the damage that can be done at such a young age,” Karidis said. “Skin can deteriorate very quickly. She could reduce the lines by improving her lifestyle, but that would mean giving up the partying."
