What was once described as a “fast fling” is quickly growing into something more.
“Leo seems very into her,” the source tells PEOPLE in this week’s issue. “He constantly holds her hand and kisses her. Nina seems to enjoy Leo’s company too. She acts very giddy around him. She has great energy and seems to make Leo very happy.”
Whether it’s vacationing on the private Bahamian island Over Yonder Cay, relaxing on the beach, or spending a weekend in Montauk, New York, or Malibu, California, the pair — who have been dating since July — have clearly been getting cozy.
Agdal, who has appeared in Sports Illustrated‘s swimsuit issue and once dated British pop star Max George, is “different,” says the source, but “doesn’t take herself too seriously.”
“She is quirky and has a very goofy personality. She seems mature for her age, too. Whenever they spend time together, Leo acts very happy. For Leo, Nina seems like a breath of fresh air.”
Though the couple do not live together, The Revenant star was reportedly house hunting in Malibu earlier this month.
