The 60-year-old Fight Club actor is thought to have been dating the jewellery designer, 34, for two years – but the pair only made their first public appearance together at the premiere of his new film Wolfs at this year's 81st Venice Film Festival - and a source has now said the pair are getting very "serious".
They told Us Weekly: "They're super in love. It is a big deal (they took their romance public in Venice.)"
Another insider told the outlet the pair bonded because they are both "hippies" at heart and share passions for art and music.
They said: "Brad loves introducing Ines to his friends because she's such a joy to be around. She brings out the best in Pitt.
"(Things are) serious between Brad and Ines. He's very committed to her and their future."
Pitt and de Ramon have reportedly spent this summer holidaying in the grounds of the French winery that is at the centre of a dispute between him and his ex-wife Angelina Jolie.
He has been embroiled in a long and bitter legal battle with the Maleficent actress over how she sold her share in the Château Miraval vineyard where they got married.
A source recently told Page Six Pitt has been "getting in plenty of quality time" with de Ramon at the French retreat.
The insider added: "He is living his life. Angelina has already done the worst thing she can do, which is separating the kids from their father."
Pitt claims he gave Jolie half the winery as a wedding gift, with the condition that if she ever wanted to sell it she had to offer it to him first.
But Jolie sold her share to a third party and Pitt claims it was a breach of the deal.
He and Jolie have also been caught in a custody battle over the six children they have together – Maddox, 22, Pax, 20, Zahara, 19, Shiloh, 18, and 15-year-old twins Knox and Vivienne.
The former couple's divorce is still pending, but they are both legally single.
Page Six reported their relationship is "so acrimonious" organisers of the Venice Film Festival, where both had films running, spaced out the premieres so there would be no run-ins between the warring pair.
De Ramon was previously married to Vampire Diaries actor Paul Wesley from 2019 until 2023.
