Things may be heating up between Jimmy Butler and Shay Mitchell.

The Bulls forward was spotted out with the "Pretty Little Liars" star last month, leading to speculation that they are a couple. As it turns out, the two are an item and continue to get serious outside of the public eye.

"Jimmy and Shay are most definitely an item, but they know being in the public eye can be detrimental to a long lasting relationship," a source told Terez Owens. "They're going to keep things on the down low for as long as possible."

Though the two were seen out laughing together in Los Angeles on a lunch date last month, Butler has continued to remain private about his potential new flame.

"[I'm in L.A.] for the sunny weather," Butler told TMZ Sports when approached about being seen with Mitchell. "I'm out here enjoying lunch, man. It's a good day for lunch."

Butler, 26, was selected with the 30th overall pick by Chicago in the 2011 NBA Draft and has spent five seasons with the Bulls, making the All-Star team twice.

He averaged 20.9 points and 5.2 rebounds per game in the regular season and has averaged 13.6 points per contest throughout his career.

Mitchell, 29, is an actress, model and author, known mostly for "Pretty Little Liars," on which she has played Emily since 2010.

Butler has bounced back nicely from the disappointment of missing the playoffs this season with the Bulls. Chicago finished 42-40 this season, closing out the campaign in ninth place, just shy of an Eastern Conference playoff berth.

Though this season snapped a streak of seven straight postseason berths for the Bulls, Butler has had a solid offseason -- even if it was an earlier one than he wanted.
