9021-Ohhh, Girl! Tori Spelling went through hell and back during her fourth, surprise pregnancy with son Finn, who was born last August. "The last thing on my mind was getting my body back," the 39-year-old actress, designer, and founder of site EdiTORIal explains in the new Us Weekly, out now. Spending four months on bed rest with a severe form of placenta previa, Spelling gained 30 pounds while carrying Finn.
Having fully recovered (Spelling also underwent emergency surgery three weeks post-birth), the former Beverly Hills, 90210 star gradually dropped the baby weight -- plus 15 additional pounds accrued over the past couple years. Now 115 pounds, the 5-foot-6 star (who shares her brood of four with husband Dean McDermott) shows off the astounding resulting results in a sexy bikini (and heels!) as she holds Finn, with daughter Hattie, 18, at her side, in the new issue of Us.
"I feel like I took off the weight safely, and I'm totally happy here," Spelling reveals to Us. One astounding fact: Despite her incredibly flat, toned midsection, Spelling can't do situps or lunges for at least a year following her surgery. "I think my stomach went back pretty well!" she tells Us.
For all the details on Spelling's diet and exercise routine -- and why she's "in awe" of her figure at any weight -- pick up the new Us Weekly, on stands Friday!
