DeVitto, who plays emergency pediatrics specialist Dr. Natalie Manning on the Chicago-based NBC drama, confirmed the news on Instagram, posting a Ross-taken smooch selfie — kissing his cheek in the black-and-white photo.
"Love him madly," she wrote with a red heart emoji. Ross, 44, liked the photo via his Instagram account.
The actress, 36, had previously teased the news of the relationship last week after attending a Cubs game in Cincinnati against the Reds. In an Instagram gallery of Cincinnati sights, DeVitto included a final photo of Ross taken from prime seats behind the dugout, drawing a squiggly red heart around his head. She included the hashtag #SaveTheBestForLast.
The former MLB catcher and Cubs World Series hero Ross, 44, ensured he will never have to pay for a drink again in Chicago after hitting a Game 7 World Series home run against the Cleveland Indians in 2016. Then 39, the Bull Durham-esque journeyman was the oldest player to hit a Game 7 dinger in World Series history. The Cubs went on to win the game 8-7 in 10 innings and the series.
Ross followed the ticker tape to "Dancing With the Stars" in 2017. With his 23-year-old pro partner, Lindsay Arnold, the couple improbably finished runner-up in the entire dance competition. Ross is divorced from his high school sweetheart, Hyla Ross, with whom he has three children.
Born and raised in Huntington, N.Y., DeVitto is best known for her recurring TV roles, including Melissa Hastings in "Pretty Little Liars" (2010-17), Dr. Meredith Fell in the CW drama "The Vampire Diaries" and as Carrie in the CW drama "One Tree Hill." In 2013, she was seen as Maggie Hall in the final season of Lifetime’s "Army Wives."
On "Chicago Med," Dr. Natalie Manning is single after moving on from her complicated relationship with Dr. Will Halstead (Nick Gehlfuss).
DeVitto's representatives have not commented further on the posting.
