Diddy‘s family is remaining committed to one another while the music superproducer is locked up … with his baby mother Dana Tran, his daughter Love and his son Christian showing support to Diddy’s twin daughters, Jessie and D’Lila.

Tran brought two-year-old Love to the game Friday night … with the baby girl outfitted in a blue varsity jacket bearing her name and her birth year — ’22. Love’s already camera-ready, pointing at the photogs at the game.

Dana’s got her own varsity jacket — a forest green one — on … and, she flashed a smile too– keeping her spirits up while the father of her daughter deals with his legal troubles.

Christian “King” Combs pulled up to the game too … showing love for his younger sisters who are both on the high school cheerleading team.

He’s wearing a pristine white puffer jacket and matching sweats … chopping it up with some pals outside the game.

Meanwhile, 17-year-old Jessie was all business … cheering on her team as they rolled over another high school 38-14 in the first round of the playoffs.

Obviously, we’ve told you all about how close this family has been amid the turmoil of their dad’s incarceration. Remember, they posted a message in support of the mogul last month and sang “Happy Birthday” to him via Instagram last week.

As you know … Diddy’s still locked up in MDC Brooklyn — a notorious prison in New York City — though his lawyers recently filed another motion to get him out on bail.
