Brad Pitt Was Flirted ‘Up A Storm’ on Set of Upcoming Flick ‘F1’ — ‘He’s Always Been This Way’

Brad Pitt was in major flirt mode while filming his new racing movie, F1, after insisting on having dozens of beautiful supermodel-type extras on the set — despite his supposedly serious relationship with Ines de Ramon, a source tells GLOBE.

The 61-year-old star, who also produced the film, “really decided to lean into the glamour of the Formula 1 world, and that translated to this movie having perhaps the hottest assembly of female extras in movie history,” an insider says. “It also gave Brad plenty of opportunities to flirt up a storm between takes, even if he was in his racing helmet or behind a mask.

“Brad has always been a big flirt; he can’t help himself. And in this case, he was like a kid in a candy store! He didn’t cross the line and actually hook up with any of these girls, at least not that anyone’s aware.”

He reportedly felt that charming the bit players was part of his job in order to bring out their best performances, since he’s the biggest name in the movie, which also stars Javier Bardem.

Brad “definitely enjoyed their attention and made a point to shower them with compliments,” the source says. “He’d engage them in small talk, tell them how hot they looked, invite them to have lunch or grab a coffee with him, that type of thing.”

Meanwhile, Ines, Brad’s girlfriend of two and a half years, is said to be expecting an engagement ring from him sooner rather than later.

“It certainly wasn’t the type of behavior you’d expect to see from someone with a serious girlfriend,” says the source. “But Brad is very much his own man and he’s always been this way.

“Previous partners have taken issue with his flirting. He’s got a real roving eye and checks out pretty girls almost unashamedly. If Ines wants to stay with Brad and build a future with him, this is something she’ll have to live with, because ultimately, Brad’s not going to change his ways for anybody!”
