Some may take this news harder than others. “Degrassi” is ending its 14-season run on TeenNick in July. The final 12 episodes will kick off July 20 with an hourlong special and end with an hourlong finale.

Dr. Drew made a big confession on his HLN show last night — he used to do drugs. He said, “I did drugs and alcohol when I was 22, 23 years old…I think I went around denying it when my kids were younger. There’s a very strict parenting rule I have which is ‘you do not tell anybody what you did in your adolescence/young adulthood unless you want your kids to do the same.” But he said since his kids just graduated college, he’s able to talk about anything. So now he’s admitting that he did coke, pot and alcohol. He says he didn’t like it that much, but he admitted, “I am not perfect. I was a screwball like everybody else. I changed A LOT since I was a student.”

Chris Pratt told “Men’s Health UK” that when he was at his heaviest, he was “impotent, fatigued, emotionally depressed.” He said he got up to 300 pounds doing “Parks and Rec,” eating 3-4 hamburgers at every table read. He said, “I saw myself in an episode and in the matter of two moments very close together, I thought, ‘Oh my God, I’m getting fat.’ And then almost immediately I did something else and I thought, ‘Holy crap, I’ve never seen myself funnier.’ And I put the two together.” But after he saw himself in “Zero Dark Thirty,” he said, “I’m going to get in shape and I’m never going to be fat again.”

Justin Bieber has pleaded guilty to charges of assault and careless driving from an incident last August. Justin and Selena Gomez were riding ATVs near his hometown of Stratford, Ontario, when he was involved in a collision with a minivan that resulted in a fight. Justin has to pay a $750 fine for careless driving but the assault charge has been dismissed.

It looks like Nicole Richie and Joel Madden’s marriage is back on track. After rampant rumors of divorce — especially with all those moving vans outside their house and both of them “forgetting” to wear their wedding rings — they’re now being seen together all over the place, holding hands and wearing their rings.
