By the way, where did you get the info? First, they're still on the Eagle website. Second, here's a blurb from yesterday's All Access:
Cume Is Up At WKGL
Congrats to CUMULUS Classic Rock WKGL/ROCKFORD morning team STEVE BRILL and DEDE DEDDENS-BRILL on the arrival of their second son, COLIN BARCLAY BRILL. COLIN was born at 5:35a on DECEMBER 28, weighing 7 lbs., 7 oz. and measuring 20" long.
Sounds to me like she's on maternity leave and he's on vacation with her.
