They dated from 1996 until 1998 after they co-starred in the Joel Schumacher-directed legal thriller A Time To Kill with Samuel L Jackson.
It appears as if Sandra Bullock and Matthew McConaughey have not seen each other much since they split even though they both have residences in Austin, Texas.
But on Sunday evening the actors will come face to face as they will both present at the Academy Awards.
She is rumoured to have dated Matthew during the filming of A Time To Kill as she was also in the movie.
