The new summer romance between Tom Brady and Irina Shayk has been brewing for "a few weeks," a source tells PEOPLE.

Shayk, 37, and Brady, 45, "have been in touch for a few weeks," according to the insider, who says "there is a spark" between the model and retired NFL star.

The source says Brady invited Shayk to "fly out and meet up in Los Angeles," where the two were spotted cozying up during a romantic weekend. "They spent the night Friday and Saturday at a house" where Brady is staying, the source explains.

"There is an attraction," according to the source, who adds that Brady and Shayk "have never been involved romantically before" the summer fling began.
