Clooney's practical jokes
The stunning British TV presenter says the handsome actor, famed for his love of pranks, recently left her soaked after leaving a bunch of water balloons balanced above a door ready to come splashing down on her.
But Snowdon - who got back together with the 'Ocean's Twelve' star last summer after a brief split - says, although she loves his sense of humour, she admits sometimes the jokes leave her fuming.
She said: "They're a little below the belt occasionally, but he does have a great sense of humour."
However, the beautiful brunette claims she is now getting wise to Clooney's wicked sense of fun, and can spot the signs when she is about to become a victim of one of his pranks.
She added: "I'm getting clever. I get a gut feeling when he's in a naughty mood."
The 44-year-old actor is famous for his practical jokes and once even put his own faeces in a flatmate's cat litter tray.
The star, who used to share an apartment with 'Spin City' star Richard Kind, put his own excrement in the tray - after convincing Richard the pet was constipated.
