Katherine Heigl showed off her fit physique in two bikinis to hit the beach in Cabo earlier this week. She was joined by her sister, Meg Heigl, for the getaway south of the border, where the sisters spent their Sunday relaxing in the sun, and then reemerged for a refreshing dip in the water together on Monday. Katherine shared her laid-back plans for her getaway on her Twitter account, saying, "Enjoying a girls' weekend in Mexico! Sun, sea, and margaritas!" Katherine's logging a bit of rest and relaxation before her schedule picks up with the release of her film The Big Wedding later this month. The movie, which features a star-studded cast including Amanda Seyfried, Robert De Niro, and Susan Sarandon, is set to hit big screens in the US on April 26.
