Brad Pitt and Ines de Ramon Look Stunning at 'F1' Movie Premiere

If life were a race, Brad Pitt would be winning ... look no further than his smoking hot girlfriend.

The A-list actor took his better half to Monday's "F1" movie premiere in New York City ... and Ines is looking incredible in a revealing outfit.

Brad's girlfriend showed off plenty of skin in a sleeveless top and skirt ... and he kept one hand on her busty backside as they mugged for the cameras.

BP's got lots to smile about ... and she does too ... as you can see, they're laughing, giggling and grinning for photogs ... having a grand ole time.

Brad plays a fictional F1 racer, Sonny Hayes, in the movie ... and he ditched his racing suit for a navy blue suit and white button shirt ... making for one super hot couple.

As we reported ... real F1 stars brought their WAGs to a private screening last month.
