Scott Disick: PDA With New Swedish Model Girlfriend

Scott Disick is no longer hiding his new relationship, because we got pics of Scott and girlfriend Lina Sandberg very openly showing affection in a very public place.

Scott, Lina and one of Scott's pals lunched at the Polo Lounge in Bev Hills. They were kissing inside the restaurant, located inside the very popular Beverly Hills Hotel.

Lina's a Wilhelmina L.A. model who knew him for awhile, but a month ago they went to Nobu restaurant in West Hollywood and the relationship changed. We're told they talk and text all the time and in the last month they've seen each other frequently.

It's a pretty clear sign ... Kourtney's history.
