Prime of her life? Thought that was the Parent Trap era.

Lindsay Lohan got lyrics from Billy Joel's 1989 song "I Go to Extremes" tattooed on her rib cage. (TMZ has the picture here.) 

Written by fellow Long Island native Joel, 62, The ink reads: "Clear as a crystal, sharp as a knife, I feel like I'm in the prime of my life."

According to the site, the 25-year-old embattled actress thought the lyric was important because "it represented where she is and everything she's been through... It signifies that she's focused."

The Mean Girls star also has the words "la bella vita" (which means the beautiful life in Italian) on her lower back.
