The rumor mill went crazy when Alyson Hannigan appeared a little thicker in the midsection during a recent family outing. Over the weekend, Hannigan and husband Alexis Denisof were photographed at the Chili Cook Off and carnival with their 2-year-old daughter Satyana. The tabloids immediately began reporting that the How I Met Your Mother actress had another baby on board. However, the joke is on them because the only thing Hannigan is expecting is some criticism about her weight gain. The 37-year-old actress quickly took to Twitter to dispel the rumors and point out that while there may be a bump, there's definitely no baby. Hannigan Tweeted, "NO, I'm not pregnant! I just ate too much carnival food, that time of the month, hurt my back & couldn't suck my gut in, and need to do cardio!" Hannigan also vowed to lose the outfit, along with the extra weight. She added, "And I'm NEVER gonna wear that shirt again!!! I do LOOK pregnant in that photo!" Even though the day out landed her in the headlines, Hannigan gloated about the great time she had with her family. She Tweeted, "The carnival was really fun! And Sati won a goldfish on her 2nd try! Put my ping pong throwing skills to shame." Next time, she'll probably skip the funnel cake.
