'Happy Days' Star Baio Weds

Former Happy Days star Scott Baio has married his longtime girlfriend Renee Sloan in a ceremony in Los Angeles on Saturday. The small religious gathering took place on the rooftop of a luxury high-rise building, with guests including Sloan's 18-year-old daughter Kalyn - from a previous relationship - and the couple's newborn baby girl, who was delivered last month. The 46-year-old actor has been dating model-turned-actress Sloan, 45, since 2005 and agreed to have the wedding filmed for the second season of his reality TV show - Scott Baio Is 45... And Single - which premieres in the U.S. next month.
