George Clooney is doing something he almost never does -- commenting about a report on his romantic life ... in particular, one that claims his ex-gf sent him angry text messages about his new gf.
The report in the current issue of US Weekly ... claims Elisabetta Canalis fired off a series of angry texts to George when she found out he was dating Stacy Keibler.
But George tells TMZ, the story "was completely fabricated in order to sell magazines. I never comment on my personal life unless it affects others...and this lie affects others."
George added this challenge to US Weekly, "Since I would be the only actual witness, I ask you to correct your story immediately, but that would assume you cared at all about telling the truth."
