The Towie star says he is the only one who could keep her under control.
Neeson, 66, was forced to deny he is racist after claiming he once wanted to kill a random black man after someone close to him was raped.
In her latest book, Gemma, who was dumped from Dancing On Ice at the weekend, confessed that she idolises him.
The 38-year-old said: “Maybe it’s the sexy Irish accent, maybe it’s the hulking 6ft 3in body, maybe it’s because if I ever got kidnapped I know he’d rescue me and kill all the bad guys.
“But Liam is one of my celebrity crushes and more than man enough to handle a diva. He doesn’t preen or pose, he’s matter-of-fact and down to Earth.
“And underneath the tough exterior there’s a vulnerability. Liam is a man I know I could take home.
“He’d behave himself and he’d look after me, buy my mum flowers and help my dad with any heavy lifting. I’ve thought this through, can you tell?” Gemma revealed her ideal men in her book The GC: How To Be A Diva.
Neeson topped the list ahead of other celebs including actor Gerard Butler, 49, TV chef Paul Hollywood, 52, and pop star Robbie Williams, 44.
