Mary-Kate Olsen and Olivier Sarkozy continue their courtside kissing and cuddling.

As they've done time and time again, the 26-year-old fashion designer and her 43-year-old investment banker beau packed on the PDA while taking in a basketball game.

The latest lovefest occurred on Sunday as the Knicks played at New York City's Madison Square Garden.

The couple began dating nearly a year ago.

And from the looks of things, they're still pretty smitten with each other.
