A representative for Liam Neeson has denied the actor's teenage son is dating troubled star Lindsay Lohan.

The Mean Girls actress, 27, was linked to 18-year-old Michael Neeson after the pair was spotted together during a night out at New York City hotspot Finale on Friday night (29Nov13).

However, a publicist for the Irish star tells New York Post gossip column Page Six the romance reports are "not true", adding, "Lindsay is friends with Michael but they are not dating."

Michael is Neeson's son with his late wife, actress Natasha Richardson.
