Brad Pitt Joined by Girlfriend Ines De Ramon For 60th Birthday Celebration

Brad Pitt is looking and feeling youthful at 60 … ringing his milestone birthday with his much younger girlfriend, Ines de Ramon, by his side.

Pals joined the Hollywood sex symbol — yes, even at 60 — and 33-year-old jewelry designer as they headed out to L.A. hot spot, Mother Wolf, Tuesday evening — a day after Brad’s actual birthday.

Brad ensured he’d have all eyes on him by showing off some loud style in a black and gold-foiled shirt … while Ines wore a white mini dress.

The couple’s been dating for a year now … and it’s his first proper relationship since his bitter divorce from Angelina Jolie.

He’s reportedly introducing her to folks as his GF these days … so, clearly things are going well for the duo.

Earlier this week, huge 60th bday balloons were seen being dropped off at the Bulgari Hotel where he was staying in Paris.
