‘He Found His Spark Again’.

Brad Pitt “couldn’t be happier” in his relationship with girlfriend Ines de Ramon, a source tells PEOPLE exclusively.

After PEOPLE confirmed that the two-time Oscar winner, 60, and the jewelry executive, 34, are cohabiting in his California home, a source says the move-in was the “natural” next step in their relationship.

“They were spending so much time together at Brad’s that it just made sense for Ines to move in with him,” the insider says. “Brad’s very happy and loves spending time with her. Moving in together was a natural thing.”

The couple was first spotted together in November 2022, with sources claiming they had already been dating for “a few months” by then. Ines de Ramon in 2023.

Previously, de Ramon, who is the head of wholesale for Anita Ko Jewelry, split from actor Paul Wesley in 2022 after three years of marriage. Pitt, meanwhile, split from Angelina Jolie in 2016 after they began dating in 2005 and wed nine years later in 2014.

“Since the divorce, Brad’s dated but never seriously,” the source says. “This is the first serious relationship, and he couldn’t be happier.”

The insider — who describes de Ramon as “kind, funny and very special” — went on to note that it’s “amazing” to witness Pitt’s revived joy.

“With Ines, he found his spark again,” they say. “It’s truly amazing to see. Brad’s a great guy. He deserves to be happy.”
