Brad Pitt and his girlfriend, Ines de Ramon, are enjoying their summer lovin’.

The “Once Upon a Time in Hollywood” star and the jewelry designer are “going very strong,” a source told People Thursday.

“They are doing great.”

Pitt, who had been filming a Formula 1 movie in Europe until the SAG-AFTRA strike put production on hold, has managed to see de Ramon plenty despite the distance between them.

“The two have been spending a lot of time together this summer as they truly enjoy each other’s company and are very into each other,” the insider said.

“It’s apparent to anyone who sees them together.”

De Ramon, 30, also has been to the 59-year-old Oscar winner’s Château Miraval despite the ongoing legal battle between him and his ex-wife Angeline Jolie over the property.

“He still keeps a residence at Château Miraval and has been spending a lot of time there and elsewhere in Europe,” the source added.

“And Ines has been flying in to see him several times.”

Reps for the couple didn’t immediately return Page Six’s requests for comment.

Pitt and de Ramon were first spotted together in November 2022 at a Bono concert — just a couple of months after she and actor Paul Wesley separated.

However, a report said the “Mr. & Mrs. Smith” star and de Ramon already had been dating for a few of months by the time of the concert.

They only got more serious from there, with the two celebrating Pitt’s birthday together in December and going on a luxe trip to Cabo where de Ramon was photographed sunbathing topless in January.

As if the romance hadn’t been solidified enough, de Ramon began wearing her heart around her neck in the form of a “B” necklace in honor or her beau.
