Under-age teen beaus LiLO’s newest vice.

LINDSAY LOHAN is on a mission to become the youngest cougar in Hollywood at age 27 – and she’s already left a string of brokenhearted young men in her wake, say insiders.

Now the out-of-control actress has set her sights on Liam Neeson’s 18-year-old son Michael, and the two have been getting cozy in New York.

“LiLo’s list of conquests is longer than her legal bills these days,” a close pal told The ENQUIRER. “She’s supposed to be taking a post-rehab break from romance, but she’s got guys begging her for dates – and she’s not saying no as long as they’re hot and under 25.

“She’s been boasting about her cougar abilities, saying she learned everything from her mom Dina.”

Although reps for Lindsay and Michael denied that the two are dating, she was spotted whisking him hand-in-hand to the ladies’ room for some private time at New York club Finale last month. The source says she’s much more open about her toy boy lovers than her 51-year-old mom, who’s been “living with a younger guy for awhile now but they only go out on the sly.”

Since leaving rehab at the end of July, Lindsay’s been linked to New York model Liam Dean, 19, and Ralph Lauren model Morgan O’Connor, 18. She also had a fling with former pro football hunk Matt Nordgren, but his days were numbered when she found out he was several years older than her.

“LiLo’s insatiable right now,” said the insider. “She’s lost ten pounds and has been showing off online with sexy selfies.”

Her hot-to-trot behavior burst spectacularly into the open recently when a source says she and a young stud got booted from a New York cab in the early morning hours after steaming up the backseat with R-going-on-X-rated antics. Enraged, the driver pulled over and bellowed at them: “Get OUT! This is not a hotel room.” Now, an insider says that Lindsay has a new goal.

“She wants to be a better cougar than her mom, Demi Moore and Kris Jenner combined!”
