General Hospital's Tamara Braun (ex-Carly) isn't the only soap-opera sexpot dropping by ABC's sitcom Freddie. Next up, Krista Allen (ex-Billie, Days of our Lives) is romanced by Freddie Prinze Jr. in an upcoming episode entitled "Freddie and the Hot Mom." Look for Allen — who, naturally, plays the hot mom in question — to air on March 29.
