Nicollette Sheridan's ex-fiance NIKLAS SODERBLOM is frustrated he missed the obvious signs the actress had fallen for singer Michael Bolton. The DESPERATE HOUSEWIVES star ditched Soderblom to reunite with Bolton, who she had dated years earlier in the mid 1990s. Soderblom now accepts Sheridan provided plenty of clues. He says, "I should have realised something was up when she started listening to Bolton's songs in the car." Sheridan and Bolton announced their engagement in March (06) - five months after she ended her relationship to Soderblom.
