Lisa Marie Presley, Elviss only daughter, shows off her 3-month-old twin girls Finley and Harper in the new issue of People.

I really wanted these babies, says 40-year-old Lisa Marie, who tried to get pregnant for two years. My blood was too thick and would clot, which caused several miscarriages. The moment I took blood thinners, I got pregnant.

As for losing her baby weight, she shared, I was unable to see my toes by the fourth month, she admits. But I only gained 30 lbs. total. I worked out up until the seventh month.

Lisa was once married to actor Nicolas Cage for less than a year.
