Heathcote, 23, and Pitt, 47, both shot scenes for Cogan's Trade in New Orleans recently, but a source close to the actress tells UsMagazine.com there's no truth to the reports that Jolie, 35, is "desperate to keep Brad away from Bella."
"Bella has never even met Brad," the insider tells Us. "She is in the movie but doesn't have any scenes with him."
After all, when Pitt isn't on set, he's spent most of his downtime bonding with his kids. Case in point? The hands-on dad took Maddox, 9, Pax, 7, Zahara, 6, and Shiloh, 4, to a screening of James Marsden's new animated film Hop on Sunday.
"Brad was really sweet and very hands-on with the kids, never leaving their sides for a minute," a source told Us. "The kids grabbed juices and carrots and candy at the reception and also made a flip book of themselves!"
The event raised funds for EBMRF, a skin disease affecting children; Pitt is on the honorary advisory board for the EBMRF medical research foundation.
