Catch the full clip — Donnell looks back on Rob’s groundbreaking career, talking about how he embraced change when others wouldn’t and used his platform to open doors for people along the way.

Police in Rhode Island just released new surveillance footage of a person of interest in Saturday’s mass shooting at Brown University.

The video shows a person, dressed in all black, walking down Waterman Street near the corner of Hope Street … a couple blocks away from the Ivy League campus.

Rhode Island Attorney General Peter Neronha says investigators believe the person in the video is the same as the person seen in different surveillance footage … according to CNN. The person is still unidentified.

The Providence Police Department announced, “We are sharing a video of a person of interest and plan to release additional video as part of the ongoing investigation.”

A person of interest was taken into police custody Sunday, but has since been released after an investigation cleared him.

Two students died and nine others were injured in the mass shooting Saturday at Brown.

Chrisean Rock is apparently taking her street-fighting talents to the ring … revealing she plans to go pro in boxing — with Ryan Garcia as he trainer — following her fight in Compton.

That’s what the “Baddies” alum said on Monday … right on the heels of getting slapped by a woman in Compton while participating in an event for families and kids in Los Angeles. The slap and words exchanged sparked a brawl, with many claiming Chrisean defended herself against multiple people.

Now, she plans to take her skills to a professional level — with King Ryan.

Getting into the sport with Garcia as a trainer is not a bad idea. The 27-year-old is a former WBC interim lightweight champion and is regarded as one of the fastest punchers in the boxing ring right now.

Garcia has been involved in several thrilling fights throughout his career — including his big win over Devin Haney.

Plus, the rapper/reality star and Garcia are cool — the two were spotted hangin’ out together Sunday at the Rams game, even singing along to a song together.
