Meet the hot mama from How I Met Your Mother! TV star Alyson Hannigan unveiled her super fit beach body during a family trip to Hawaii on Monday, Sept. 30. Rocking a sexy string bikini, the 39-year-old actress showed off her washboard abs while taking a dip in the Pacific Ocean.
Despite how she looks now, the actress hasn't always felt confident in her own skin. After the birth of her daughter Keeva in May 2012, for example, Hannigan tweeted, "I think by Hollywood standards I'm supposed to be in bikini shape now that my baby is 4 weeks old. My workout goal: Food drops in lap, not on belly." She also joked at the time, "I still haven't lost all the weight from my first daughter. Oh well."
