'30 Rock' Actor James Marsden Knocks Up Model in One-Night Stand

Even in this day and age of condoms, birth control and the morning-after pill, it's still possible to get knocked up from just one misstep. Here to remind us all of that fact is 38-year-old actor James Marsden, who plays Tina Fey's love interest on "30 Rock," and who has impregnated 24-year-old Brazilian model Rose Costa. Costa and Marsden spent one night together in Miami a few months ago, according to the New York Post. They then parted ways, but after several weeks, Costa called Marsden to let him know she was carrying his baby.
But that's not all there is to the story -- Costa was reportedly in a serious relationship with actor Chris Santos when she knocked boots on the sly with Marsden. Santos, by all accounts, is devastated, and the two have broken up.
Marsden, for his part, just split up a few months ago from his wife of 11 years, with whom he already has two children.
