LUKE PERRY GIVES JASON PRIESTLEY PARENTING ADVICE

Former Beverly Hills 90210 stars Luke Perry and Jason Priestley are still best buddies. And now that Jason has finally become a father, Luke tells OK! that he's advising his one-time co-star to 'sleep as much as you can! You need your strength.'When OK! caught up with Luke, now starring in HBO's John from Cincinnati, he said he'd just phoned Jason, who appears on Lifetime's series Side Order of Life. 'We have always talked about everything. There's no subject we don't touch and we don't kid glove anything,' Luke said. 'That's why we've been able to be friends for this long.'Luke, who is a divorced dad to daughter Sophie and son Jack, revealed he hasn't visited Jason, his wife Naomi, and their newborn daughter yet. 'I'm going to give him a couple of weeks to get used to it, then I'll get in there.'By Carole Glines
