"I saw that. And I called her on it last night," the single movie star told Entertainment Tonight at Saturday night's 2013 BAFTA Britannia Awards in L.A.
What Clooney's referring to was an interview Bullock gave to U.K. morning show Daybreak in which she admitted that despite him being Hollywood's most eligible bachelor, she doesn't lust after Clooney because she knows him too well.
That may be the case, but by George, she certainly calls him a lot—that is, if you believe the smirking 52-year-old actor's signature tall tales.
"Let me tell you about Sandy. Yeah, she may say that she's not all that attracted to me. But she calls every night at three in the morning drunk," Clooney joked. "'Hey George, what are you doin'?' Nonstop. And then I just send her a bottle of tequila."
As for why he and Bullock have never hooked up despite having been friends for more than 20 years, the Oscar winner explained to E! News last month at Gravity's New York premiere that he hasn't gone there because "she was dating one of my best friends."
"There's a certain bro code, you know what I mean?" he told us at the time.
Another old friend, Julia Roberts, meanwhile presented Clooney with the Stanley Kubrick Britannia Award for Excellence in Film at the ceremony.
Commenting on the wonderful toast she feted him with before handing him the prize, the handsome hunk said with a wink, "I gave her a little cash for that."
