The rumour mill went into overdrive yesterday when Liam Neeson's "incredibly famous" new girlfriend was reported to be Kristen Stewart.
Those claims are "stupid" and the result of "meaningless speculation," a spokesperson for the Taken star says.
Neeson sparked the rumours after admitting he had moved on with a new girlfriend after losing his wife Natasha Richardson in a skiing accident.
Neeson, 63, said he was dipping his toe back in the dating scene, saying he is involved with an "incredibly famous" woman.
"I'd embarrass her if I said her name, she's incredibly famous. I'll have to do my best for her. It's amazing how far a simple bunch of freshly picked flowers will go in a lady's life, I find," he said.
Super sleuths on the internet reported it was 25-year-old Twilight star Kristen Stewart.
A report on Jezebel sketchily suggested Neeson and Stewart visited New York nightclub Tao NYC at the same time on January 5.
But a representative for Neeson told GossipCop the rumour was "stupid".
The same rep told The Independent it was the result of "meaningless speculation".
Despite the denial, Twitter quickly lit up over the rumours.
Neeson started dating Richardson, of the famous Redgrave acting dynasty, in the 1990s, with the pair marrying in 1994.
The couple had two sons together, Michael and Daniel. However, Richardson died in 2009 from brain injuries after falling on the ski slopes in Canada and bumping her head.
Stewart's previous relationships include her Twilight co-star Robert Pattinson and a brief liaison with Snow White and the Huntsman director Rupert Sanders.
She has reportedly split up with her girlfriend Alicia Cargile.
