CALISTA FLOCKHART is keeping a close eye on her hubby HARRISON FORD after he enjoyed an intimate dinner with gorgeous home-wrecker AMBER HEARD, say sources.

Bisexual beauty Amber, 26, reportedly broke up Johnny Depp’s longtime rela­tionship with his baby mama Vanessa Paradis – and now she’s getting close with the 70-year-old “Indiana Jones” star, confide insiders.

The young bombshell, who’s been filming “Paranoia” with Har­rison, enjoyed a private supper with the aging hunk on Aug. 28 at Da Umberto, an upscale Italian eatery in Manhattan. She radiated sex appeal in a sheer white top and skintight black pants.

“Amber was dressed to kill and she’d really lacquered on the makeup,” noted a source. “There was no way that Harrison could have been immune to her charms.”

The source goes on to say that it was just a friendly dinner during which they discussed the movie, but Calista couldn’t have been happy about it because she’s well aware of the reports on Amber’s reputation.

Amber and Depp, 49, reportedly linked up while the two were filming “The Rum Diary” in 2009 and continued to see each other after filming wrapped.

In the meantime, Depp’s 14-year rela­tionship with Paradis, with whom he has two children, collapsed.

Then in a startling turn of events, Am­ber kicked the superstar to the curb and abruptly went back to former girlfriend Tasya Van Ree. “Now she’s split with Tasya again,” said the source. “And I think Am­ber has a little crush on Harrison.”

That won’t sit well with 47-year-old Calista.
